Heh...yeah, you actually have it kind of backwards, as Accurate is the counter to Stealth.
In turn, 'Super Stealth' ends up being a counter to Accurate Shot.
But as ChuckaFett pointed out, there aren't really that many pieces in the game with Accurate, so Stealth pieces can still be VERY useful in the right situations.
There are also some really interesting interactions with Stealth and Super Stealth where you can cause an opponent to not be able to make any attacks at all. Basically, if they are at a point where they are less than 6 squares from a Stealth piece, but not adjacent to it, then technicaly, Stealth isn't in effect (closer than 6 squares) so that piece counts as the closest target, but then again, you still can't attack it because you aren't adjacent. So there's some strange situations that you can really make work for yourself as well.
