I’m surprised how little I play my STLE currently. Bad timing though, I got in a rush of getting a bunch of home machines at a time. In the future I know it will have a prolonged period where it dominates my home play. It’s also one of the “true” LE’s which doesn’t hurt. It gets my vote over MB, even if you already have Spider-Man.
Additionally If you’re a solid player and don’t have a friends/novices/noobs over often then MB would certainly have an increased chance at getting old faster.
BUT if you have people over all the time though... I change my answer to MB.
