Big 4 >>> Investment Banking

Generally speaking, Big 4 CF offers the best exit given you practice all the skills and responsibilities required of an analyst in IB. This means anything from modelling, developing the model with the client, co-ordinating different DD streams, origination, bidder meetings, through to close etc. Unsure one what the third bullet is but this seems to be representative of a B4 CF team, however be careful as some B4 teams have modelling teams who really only perform fairness opinions and audit support - neither of which is representative of the deal life cycle. 

TAS gives you exposure to the M&A process, you will be liaising with PE houses and IB's to produce a report that is ultimately circulated to potentially interested parties. However you'll build a somewhat specialised skillset as you will be working on only one work stream (FDD/TAS) in the deal process, and won't get exposure to deal origination and closing. 

Infra i'm less well versed in, someone else with better experience can help. 

Ultimately it depends on your end goal. If its M&A, then I would say 'Entreprise Deals' - although check in advance what this team actually does, secondly TAS and thirdly Infra. If you want to work in Infra then the reverse is true.
