Many threads have been created over the years concerning which group is best, what exit opps are from each group, etc.
While strength of groups change with the tides, i.e UBS healthcare left for Jefferies , I'm only going to comment GENERALLY and on my OWN experiences at a mid-tier Bulge Bracket bank, so if you disagree, you're probably right so feel free to share your own experiences at your shop.
Now, if you're at an elite boutique or mid-market, it's going to totally depend on your shop and what that particular shop is good at. Example: Qatalyst and Allen obviously have their own niches that they're known for and you'll just need to do a search on that yourself.
With that said, hopefully this thread helps to answer a few of the repeated threads about what group to pick.
