Help me choose between two BB offers - Europe

First time posting, but long time WSO user - this forum has been so valuable for me. Currently, I'm facing an important decision in my career / life and wanted to know the thoughts of the community.

TL;DR: have to choose between a country team (American BB) and a sector team (Tier 1 BB)   

I'm currently working at a Tier 2 Bank (think Nomura / SocGen / BNP / HSBC) as an M&A Analyst in my home country in Europe. I have roughly 3.5 years of total work experience (I started at a regional MM firm and did some downgrade during the way, but I believe it was worth it).

Some months ago, and seeing how hot the market was, I started to think about lateralling to a better bank (BB / EB) looking for i) better pay and ii) better exits (i.e., trying to maximize exits from my IB years, could be PE, CorpDev, etc. but wanted to keep options open). I also do not neglect the possibility of having a career in IB.

Fortunately, I have received two offers that I believe are strong but also very different (both for Junior Ass position):

• American BB (BAML / Citi) in my home country: it's the country coverage team

• Tier 1 BB (GS/MS/JPM) in London: sector coverage team (Consumer / Industrials / Healthcare / TMT)

How I see the situation:

-  American BB in my home country:

(+) I want to live in my home country in the medium - long term, and this is the easy choice. My friends are there, also my girlfriend (even though its a 6 months relationship, and I believe she would understand that I left the country for a few years), my family is close, etc.

(+) Pay is extremely good at this bank. Cost of living is of course very much lower than in London, which would result in amazing savings as I have a frugal lifestyle. I could buy a good flat and pay the mortgage easily in a few years

(+) Track to VP would be 1 year faster vs the competing offer

(-) It's a country coverage team. I'm afraid that execution responsibilities could be assumed by product / industry teams in London (at least for larger deals - in smaller ones, I think that the country team would have a bigger role since it is not "worth" to devote too many resources). I believe that part of my job could be just updating monthly pitches / presentations to cover the relevant clients in my region and help Directors / MDs to maintain relationships.

(-) Additionally, I do not like some industries that are quite relevant in my country (like energy or infrastructure) and would have exposure to them.

(-) Dealflow might not be very strong. M&A in my country is a limited market, and there are many competitors, so its hard to win mandates. I have been doing M&A during all my career and I enjoy it, and I wouldn't like to do a lot of ECM or other products. This bank is in general very strong in financing, so I'm afraid M&A wouldn't have a big weight

(-) The MDs at this bank have international experience (worked in NYC / London for several years). Its true that there are several directors that didn't do the same. 

• Tier 1 BB in London:

(+) I like the sector. When I was at the MM firm, I specialized in it and this helped me to justify the rationale behind my application to this team. It's also a broad sector, doesn't pigeonhole you and has good PE exits (maybe growth equity could be more difficult)

(+) Regarding pay, its true that base salary would be roughly the same as the competing offer (with a much higher cost of living), but bonuses could be stronger

(+) I believe that the team is more seriously organized that the country team (which is more like a satellite office), and there are not so many people at the top, it is more balanced which could help me to gain responsibility

(+) Having worked in London at this bank would open me a lot of doors, and wouldn't close doors at my country (still would have 3.5 years of experience there, and could easily justify story of returning home)

(?) I am still doubting about the role of industry teams at this bank. Interviewers told me that they do market / company parts in a CIM and that they tend to also build the models, giving the M&A team the process work, but this seems a bit too good to be true. Of course, industry teams are in charge of pitching, but I can accept this as long as dealflow is good

(?) According to interviewers, this team does 60% M&A, 40% other products (ECM, Levfin) which would give me (I believe) more M&A exposure than the country team, and also larger (not necessarily "better") deals 

(-) I believe this team is not among the strongest teams in this bank (M&A and some other industry teams are def stronger), so maybe this would be discounted by headhunters / PE firms in case I would like to exit at some point

(-) I would have to leave my country and go to London to start a new life. If suddenly I have an awful time at work (bad bosses, etc.), life could turn out to be very hard for me

For me its clear that leaving cities away, the Tier 1 BB is a better offer, but it is hard to let personal factors out of the decision.

I consider the London offer to be very interesting as it would be great for my CV to get international experience, I would work on a sector that I like (and avoid what I don't like), I could always return to my home country if I hate it and it would give me very good exits. For now, I don't know if I want to do PE, stay in banking is always an option too, or even to do something more chill like CorpDev when I have good savings

A more short-term view leads me to think about staying in my country with amazing quality of life, friends and girlfriend, take the offer, buy a good flat and pay the mortgage in max 5 years

Many thanks if you read all this. What do you guys think?
