You really have to just read a lot and try to decide what is best for YOU and your career. Pay? Upgrade time? QOL?
It is surprising what other details of a contract can do to add to QOL.
When was hired into the regionals, I had a several choices for interviews. I choose a solid contract and QOL. IF I had chased the upgrade and home base, I would have upgraded in 3 years instead of almost 6.
A flip side to that is a friend who choose home base. He upgraded quickly, got his 1000pic and then went off to one of the best companies out there. He has since lost his life in a crash.
Another good friend ended up commuting, but upgraded quickly and is now super senior at the company. He makes good money and has choosen his family 1st with a good schedule and a simple drive to work.
I won't for a second, 2nd guess my decisions as it has led me to my current job, which I love. You should have, or at least will start to hear that you can't really know if you did your airline career right until you have retired.
I am a bit out of touch with the regional market in the States now, but keep reading. (fast since you have a offer) Skywest is a good company. No matter which company you go to, there will always be "that guy/gal", so ignore the sarcastic stupidity when it comes to comments about your career.
Go with your gut and do what you think is best for you. Just my $.02
