I did the jump from a similar gig into a major, best thing I could have ever done in my life, and the only negative is that I did not do it before.
QOL is subjective, to me the control of my schedule, freedom to work more or less as I chose, and un-stressful work day is far superior than the one in a corporate.
As far as quantitative analysis, things like remuneration, retirement, amount of real days off, safety statistics, these all blow the corporate jobs off the water, even after the initial pay cut.
I would try everything possible to leave in base, avoid the commute, and you will not believe how easy your life will be. The time and energy that you will have to spare.
