IMO one is worse than the other because the wrong thing gets activated and you have to recover from that.  In the case of moving finger off what you wanted in theory nothing should happen and you would have to try again but you wouldn't have just performed an action you don't want.  But, yes, to your point some of this is user agent related, however, at some point we have to realize that this might not get solved by many common user agents in the near or even medium term.

I shamefully admit that I hadn't looked into those. But now that I have, this makes me wonder: since there are two conflicting scenarios here - a user who WANTS to activate a control but may lack the dexterity to keep their finger over the control, and a user who accidentally tapped down on a control and DOESN'T want to activate it - is it right for an SC to prefer one scenario over another and make the other one non-conformant? 
Or is the whole problem (depending on which scenario you're in) one that is best left to UAs to address (so a UAAG one)?
