Regionals all suck, some less than others, but the suck is real. The best regional is the one in the rearview mirror. So go to the one that will get you through the process as quickly as possible, ie, 121 box checked, PIC and a major job. At this level QOL is your mortal enemy because, you will get comfortable and stop moving forward, because life gets bearable. On the flip side, go to a regional that sucks, your logbook will be up to date, apps out and there is no illusion about wanting to move forward. Get in, get out, period.
