Please advise: Offer Dilemma (FT analyst)

I'm very fortunate to have received multiple offers and I have narrowed it down to 2 offers which I'm having a hard time deciding between. 

Offer A: AM division of a mid-tier bank, focussing on fund marketing/capital raising and analysis it seems (though the title of the role sounds more technical - Product Management). The funds are extremely strong though in its commodities asset class, and the team could even be said to be the best globally for that particular asset class. Exits to PE places that specialize in that asset class should be quite easy but it looks like most people stay for long and can enjoy mobility within the firm. Team is extremely small and new compared to normal BB which will have an analyst class i.e. I might probably be joining alone or with just one other analyst.

85k USD base. Role based in Asia HCOL. 

Concerns: The "marketing" aspect of the role, despite the title sounding more technical eg Product Manager, might prevent me from moving to more technical roles. Being pigeonholed in commodities in case I hate it. The nonexistent "analyst class" to serve as support board and work together. Lower base. Not as big a rep compared to other offer.

Offer B: Investments role in Private Bank of a top PB in the US. Scale is huge at the firm, supposedly the mobility is great, said to be one of the best PBs globally so has a great rep. Not sure which asset class I will be allocated to work on though, also not entirely sure how "investments" the investment role will be. Standard analyst class size, with a standard training program.

100k USD base, Role based in the US HCOL city. 

Concerns: Would moving to serve institutional clients be hard? If I want to work in Asia eventually, would this be a boon or bane? Relative to the other offer, would I find it more challenging to head into AM roles or do they like that I was at a high-tier bank? Does it matter which team I'm placed in for investments? Could I end up pigeonholing myself there and then as well if they give me an asset class I don't like?

Some other factors: I am not entirely clear on career direction so optionality is important to me, but I am not closed off to specializing in something too if there are great options/exits. LT would like to be in Asia to work in the buyside. Bonus for both are uncertain, but I'm not banking on it. 
Thanks and feel free to ask me clarifying qns. Have to be brief to maintain some confidentiality!
