If the commute is equal I'd go with the one that paid more and offered me more chance to move up in seniority quickly. Despite what most people in this thread are saying the majority of the guys I personally know with major class dates are turboprop check airmen. There's more movement on the turboprop and they had the chance to put check airmen on their resume quicker which lead to the major interviews. People keep saying jet time is better than turboprop time but from what I've seen personally it doesn't seem to matter.

An airplane is an airplane. I wouldn't worry about what you fly. Go to the company that has the most movement and best pay. Chasing a jet only to sit reserve in the right seat for years won't make a good career.
