Well, to be perfectly honest, the general consensus seems to be that while the controls are solid for the most part, occasionally little blips happen like when you want to pull your sword out it doesn't always happen on the first try, same with slashing and the spin attack(which has happened to me on occasion). I don't think I've read any reviews that have denied that; where the split occurs is whether or not this is an actual problem that affects the quality of the game, or if its so minor it shouldn't be counted as a problem.
As for my opinion...for the most part it isn't that big a deal, but it can be a tad annoying when you need to get that sword out or slash in a pinch, and it doesn't immediately happen. At some points it's caused me to take damage, but not so to the point that I died or anything, so I wouldn't say it's THAT annoying. However, if you're a controls perfectionist and something this minor will genuinely affect your enjoyment of the game (Which isn't a bad thing), then it wouldn't be so bad to wait for the Gamecube version.
