i think at the end of the day, unless they're are massively grown strains, then most people who will be able to answer will come back at you with a "bean A is fantastic, really really stoney" but will not have any experience with seeds B-E whereas other people will come in having experience of B, but not A, C, D and E etc.
i say just take a pick and see what it's like for yourself, chances are whatever you pick you're gonna be getting a pretty good smoke. for stoney (that to me shouts lack of movement, couch lock, little activity etc etc, i'd be looking at indica's.
