I've been working up an excel spreadsheet with this kind of information on it for about a year. I would offer to share it but a lot of it is controversial so I defer on that. But you could start one of your own and put a row for each regional on it along with any aliases they use, and have a column for what you want to keep track of such as reputation, base locations, quality of life, fleet size, application minimums, upgrade time, payscale, perks, benefits, training bonds, whatever you care to track. Then as you read this forum you can update it every time you read something noteworthy. In 6 months you will know most of what there is to know and it will largely be free of bias. By asking for random responses you invite nonrepresentative viewpoints, whereas a variety of responses over a number of months is far more accurate and is not that hard to work up.
