Do what makes sense for you and what you want. If there is a regional based near the biggest city where you live I would say do that to not commute or find and easy commute. Pay for the most part is pretty close at all of them. Also what do you want to fly? Don’t listen to people who say don’t go to the shiny jet if that’s what you want to fly then do it! Remember it’s career progression. Most people think they are owed something and complain about every little thing and future trip constantly I would say stay away from that. Another note probably 85 percent of the people I flew with at the regionals didn’t want to upgrade when they had the time so just remember that too. Enjoy there is no right or wrong job to pick other than the right one for you
