.25/.5$ harder than .5/1??

Hi guys,
If have recently moved from stars to full tilt and was aghast, at how much harder the games there were (specially aggression wise, but prolly I just suck). What I found most interesting is, that the games of .25/.5 were IMO more difficult to play than the .5/1. I know it sounds stupid, though someone said in some thread (not sure which one),, that the .5/1 and 1/2 levels are easiest to beat online. Thoughts on that?
