if he goes to the E he's gonna be an upper midcarder and MIGHT get an eventual push if he stays healthy, a top guy gets hurt/takes time off, AND he impresses the brass
if he goes to AEW he'll get a rocket push to the top for about a month, then lose the belt to mox or hangma'am and only ever show up on Dark
i don't know which is the better option, he's only 30 so if he goes the E route he'll be 33-34 by the time he really starts getting traction, and that's assuming they don't stick him in NXT to boot
