Flightsafety sets the standard for professional simulator training. They are the biggest and spend the most money developing new simulators. However I believe that they do not do that good of a job of maintaining and training on some of their lower level sims (ie King Airs and Lears). Having said that, there is some real talent with the long time instructors at FS (Dick Lathrobe LGB, also the King Air manager in ICT, and the Lear manager in TUS). In short FS is the most professional facillity, the Citation sim in LGB is next to the MD-11 sim that American Airlines is training in, the King Air Sim in HOU is next to the Emb-120 sim Coex is using.
Simuflite has the nicest facillity, the Taj Mahal is a very nice place to train in, and my personal favorite. I also prefer the Stimuflite manuals to FS's.
Simcom/Quickturn are much less professional, you will likely mingle with owner-operators, and people trying to save a buck on training. I was also not very impressed with the manuals at either place. However, if you absolutely need to get some recurrent in for cheap and quick this is the place to go. I wouldn't recommend it for initial. The instructors might spend more time with you individually, but they have less knowledge of the aircraft. Again this is in general, there are some very knowledgable instructors at Simcom/Quickturn, and there are some idiots at FS/SF
Overall, it really doesn't matter where you go, as long as you get a Level C or D sim. Once you get in the sim you're going to be doing the same thing every place you go. They're all 142 schools so they're pretty much scripted by the FAA as to what they have to do; i.e. day three is hot and heavy, and you always have to do the same manuevers on the checkride. The only real differnence between the places is getting a good instructor and getting good ground school, unfortunalty most of the good instructors are teaching the Gulfstreams and Falcons.
