I'm holding MSP one month after IOE at Compass. So much movement in MSP right now that you could get it almost right out of training. For take home pay adding three zeroes to hourly is exactly what I'm making on first year FO pay after tax.
I'd say the only place that Endeavor has Compass beat is pay, and that won't last forever. You will have seniority quickly at Compass. Lifers almost do not exist here.
