I don't think there is a better regional then another right now. What one person thinks is better another might not. What you really have to ask yourself is what is most important? Quality of life? Pay? Upgrades? Equipment? Find out what is most important and go from there. Quality of life would be working for one that allows you to live in base, decent pay, days off. Pay, well that is obvious. Upgrade times can change on a dime. I came to Eagle 4 years ago knowing upgrades were 10 years while other airlines like Skywest was down to 4. Now look how the tables have changed. It is so hard to pin point quick upgrades these days. You want to fly a shiny CRJ-900 or E-190 go to the regionals that offer them. To sum it up figure out what it is you are looking for and go from there. My personal opinion would be quality of life is key. Without it your hobby will turn into a job you dislike.
