Train at an FBO who YOU are happy with. What may suits you may not suit another. Find one with good instructor to student ratio. Good access to the aircraft and various facilities like ILS, NDB & VORs.
Take the time out to visit various FBO/Training centres. If you can, make sure you have some idea about what each stage of the training should take. (I think you may be able to get that from LASORs)
In the end, the license is exactly the same. There is no difference nowadays.
Make sure who ever does your IR is very thorough. That's the "real" test so to speak.
