Transaction Advisory at Big 4 Advice

I currently have offers from multiple big 4 Accounting firms in the Transactions Advisory practices. I was hoping to get some advice as to which may be a better place to start my career? My #1 priority would be exit ops, which firm is most respected in the industry and can get me to either an IB analyst position (BB or Boutique), Equity Research, Grad School, or straight to PE if that's even reasonable. From what I've gathered, it seems like KPMG is the best option, but I'm hoping to get some more insight before making a decision.
