How is the multi player going on xbox?

[SURE SHOTZ 247]

I was wondering what the situation is on xbl with regards to the mp,i have bop on ps3 and while im enjoying it im having trouble getting games going.
I realise this perhaps isnt the most popular genre of game and that probably has a lot to do with it, and while there does seem to be a lot of arcade action i cant seem to bring myself to even think about joining them.
So i am now thinking of swoping my ps3 copy for an xbox version unless its going to be the same and thus futile!
