You guys notice any difference between the PSN / XBLA communities? Which is more robust?
I played the last three installments (mostly SP) on XBLA, but with Sealed being a thing now I may want to mess around online with some gaffers a bit. I'm just not sure if it's worth picking up XBLA "Gold" again. If the PSN community is just as good then I'm heading there.
I would say PSN because its usually free as part of PSN+ sometime down the line and tons of players have it.
Having said that i would go Steam for the text chat and big picture mode if you like that sort of thing.
