Other than the framerate osu!lazer on taiko also got a different way to calculate accuracy compared to normal, I've done multiple checking and apparently:
-When on Osu!taiko you would get 10 hits with 9 Perfect and 1 Good, The accuracy goes to 95%
-Instead on Osu!lazer if you would get 10 hits with 9 perfect and 1 Good, The accuracy goes to 93,33%
So let's suppose every Good note gives you 2% more accuracy less than on normal, that's a huge difference which can variate the accuracy by a lot, as example on maps I'd get 98% accuracy fc, I'd get 95% if not even less.
Those also are also only the Good notes, considering all of this, Misses would make you fall by even WAY more accuracy.
