Auditor Gets Offer From Both Regional Botique And PwC CF Team, WHICH ONE?

Hi everyone, I am currently going through an important life decision right now.. Having spent about 2.5 years in PwC audit, I am currently able to secure two offers, one from PwC CF team and one from Regional boutique IB. My goal is try to get into PE/VC and I am currently in NZ but quite keen to expand to AU in the future. 

The regional IB has these considerations: (1) IB analyst sounds better ... (2) have a variety of exposure to M&A, debt advisory (probably a bit more emphasis on debt advisory: probably 1/3 in M&A and the rest for debt advisory); (3) straight off the bat lots of involvement in the preparation of IM, pitch books, term sheets etc; (4) They have a small PE in the firm too, which is too small to be in but i guess they do some work for their own PE shop and this will be a good experience as opposed to being the sole financial service provider, I guess this is quite important for moving into pe too? and (5) there is a profit share scheme... 

For PwC, the pros are more around it is M&A heavy, the name is probably bigger in M&A compared to the regional IB, I don't have to take a step down so pay is a little bit better than regional IB. The only concern is probably around the fact that I may have to start with the valuation and financial modeling first and have to slowly move into the M&A advisory later.  

Anyone has experiences or take around this? If I want to move into PE/VC in the future, which one would be considered a better choice?

Anyone who needs advice on moving from audit to IB/CF I am keen to answer too :)
