I instructed in the Swiss program for about 2 years when I was there. Everything Blizzue said is right on. From my experience, the Swiss and RWL instructors were all pretty happy because they had motivated students, a good schedule and lots of billable time.
One added benefit I found when I went to my current airline was the similarity. The Swiss "SOP" and everything they tell you to teach is designed for airline operations. All the flows, the profiles, etc. etc. are what you are going to be exposed to later in your career. I wouldn't say that you'll be a maverick in airline training, but the exposure will certainly help.
The Swiss program was extremely organized and regimented. The instructors are respected more, and are expected to do a little more work in terms of student evaluations and instructor meetings with the TRS and the chief pilot.
The students have a lot riding on their training in Florida, and are accordingly motivated. The students are also closely monitored, and weaknesses are found early, with everyone from the student to the chief pilot and TRS getting involved to either turn the student around, or send him home....much different than the 141 side of things.
When I was there, the RWL instructors had essentially the same experience with their students. I think you'll enjoy either program, but I'm biased, so I'd say head over to the Swiss side....you even get a funny looking tie to make you feel special
Slight hijack: Who's running the program these days and did they get rid of the Senecas???
