Well, it all depends on what you think the future is at the current shop. I mean, gone are some of the perks like a short upgrade (as I see it). So, are you going to be at a regional for a while or will you have the quals for a legacy or whatever other flavor of flying you want to move on to?
Basically, I'm saying that if you're going to be in the regional world for a long term ride for any reason(5+ years), you may as well go someplace that will be able to give you a better wage and has the hiring capacity to allow you to have better than 6 on 2 off all the time.
On the other hand if you're planning and qualified for a 1-3 year stint in the regional world, I'd say it isn't worth losing the time invested already and ride it out where you're at until something bigger and better comes along that doesn't say "Operated By:" on the side of it.
As for me, I'm going to be in the regional world for a while to finish up a 4 year degree, so I've been considering a move myself to help the rainy day fund.
All that said......I'd say you'd do better at a few other companies in the long run as far as QOL and Pay go than G7.
