After a few practices on Stepmania and another visit to the Union, I think I'm getting quite good at Exceed 2 now. Playing it is rather like learning DDR all over again, but I can now read songs of difficulty 5 to 6 fast enough, and find my way around the pad well enough to pass them. I'm certain that the game's more difficult than Euromix 2, though, even ignoring the different layout. What's mildly distracting is the way that arrows scroll off the screen rather than burst even if you hit them with a slightly off-beat hit, so you think you've missed them.
It turns out that the only thing you have to do to get a chance at the scoreboard is complete a game, rather than complete a preset course as in DDR - this means the difficulty is in finding high-rated songs that you can pass without overdoing them and collapsing/dying in the middle. So far I've found "Beethoven Virus" and "Vivaldi Winter" decent songs for this, with the only drawback being the distracting faint whirring sound as the respective composers turn rapidly in their graves.
