I am assuming you talking about spooled/standard rear stands. Go spooled. I don't like the standard stand at all. The pads make putting the bike up and down alone very difficult. Get a little oil on the pads and the swingarm slides all over the place. Spooled is the only way to go.
As far as the front stands go I like the one which picks the bike up from under the triple tree as opposed to the fork stand.
BTW, you need a rear stand in order to use the front stand.
