This might be hard for any of us to comment as as we have all either gone to Bombardier or to FSI.
I have been going to Bombardier for the last 3 years, and cant fault them. (well there is one older Instructor who is on my no fly list, he was incredibly derogatory towards my low time FO and is really quite a rude old guy). The ground school is good at DFW and they have a whole wing and lots of bits of the plane in the basement you can go and play with, and a couple of FMS trainers if you arent used to the sillyness of the Universal. Plus I think from a Trainee perspective the Bombardier / Simuflite facility is better for a student, and its huge!
