I'm going to go out on a limb and say "All of the above."
Only speaking from personal experience, but my first flying job after instructing was for XJT, flying the ERJ as an FO. I did about a year there before being furloughed. When I hit the street, I had a little over 550 hours of jet time, which was the entire sum of my turbine experience. During my furlough, I got my ATP and flew 402s (probably the same 135 gig you're talking about), which provided me another 1500 hours of multi PIC, mostly single pilot, mostly in the northeast, in some rather challenging conditions. Naturally, I expected that future employers would brush off my Cape Air time as "just piston twin time," but in fact, the opposite happened.
That 402 time opened doors I wouldn't have ever expected possible. Instead of going back to XJT (or going to fly for another regional), I was sitting in interviews and 121 groundschools with guys I'd never thought I'd be competitive with, at companies I never thought I'd see without turbine PIC. In reality, that 402 time was huge, regardless of the types of motors attached to it. It was PIC time, and well, PIC is king.
I strongly encourage anyone with the opportunity to go fly for Cape Air (or similar operation) and build PIC time. Once you get a good amount of it on your resume, then go out and fly right seat somewhere. It will pay dividends later.
Actually, let me relate a story: A friend of mine was a Cape F/O, hired with about 400 hours. He flew the 402 for about 1000 hours, then right before going to upgrade, he got antsy and decided that he wanted to go fly for the regionals. I tried to talk him out of it, to convince him to at least get his ATP and do a year as PIC. Unfortunately, he did indeed leave the company, and now he's lost in the regional shuffle, uncompetitive to move on. As much as I've wanted to help him get out of the regionals, he simply can't do it; he doesn't have any PIC!
Seriously, PIC! Go fly the 402 for a year or two if you don't have a good base of 121/135 PIC already. It's not much time, you can go fly jets later, and it'll pay off in the long run.
P.S.: Don't get trapped in the "Pay/QOL" thing yet. Yes, that's very important...eventually. For now, you need to do work on your resume so that you can be competitive later on.
