If you anticipate more than a few years at any regional then your choices are much fewer for any stability.
Any wholly owned should be a first choice, I’d do Endeavor first, Envoy second, PSA third... even PDT; then both Skywest and Republic.
The smaller places will go through attrition based shrinkage, eventual mergers-consolidations and bankruptcy buyouts.
As hiring gets harder for smaller places it’s hard to upgrade or even hold your seat when not enough are coming in behind you. The mainlines control the flying. They aren’t going to starve their WO before taking the flying back to their own regionals.

PSA has a better QOL and pay right now, but Envoy is in negotiations to fix theirs. Oh, and even Envoy DECs are not automatically getting NY currently, so that isn’t an automatic as somebody had earlier alluded to.

If you’re going to commute. The WO travel benefits are better, and if it comes down to a compass guy or a ENY-PSA guy getting on anything AA/AE the compass guy is SOL. Same with Endeavor and Delta. Little things like getting your first commute choice add up to QOL over time.
