UBS vs Raymond James

That depends on whether or not you're a good candidate for an independent practice.  Answer that and you'll have your answer.

I like the double cheese at Mcdonalds…

If you were an FA in downtown Cleveland, for example, and you enjoyed the atmosphere UBS might be a good fit.  On the other hand, if you were based in a small town office with 2-3 reps the rj model might be better suited to you.  Of course, there are many other issues to consider.  In either case, go talk to the local managers/producers.  Additionally, some of your peers should be able to give you some good information on those offices in your area.
