I think people should only offer info on their respective company.
New hires at Endeavor are getting MSP right away. They say they are working on extending the SSP in some form to new hires but nothing is official therefore take it with a grain of salt. The retention bonus is a nice pay boost. It also seems like they want us to keep the 200 since they threw this kind of money at us. But it is only my opinion. Best of luck in your decision.
