Yes, the general principle is that the higher up you are, the more you feel. Interestingly though is that in the last few weeks we’ve had 2 small quakes both of which I’ve felt, living on only the 3rd floor, while many of my colleagues / students have not, with some of them on higher / similar floors. And their intensities have only been 2 or 3 in Hsinchu. I hope this says nothing about the quality of my housing…
Some interesting trivia for you: Everyone talks about how terrible 9.21 was, and in terms of damage and loss of life at the epicentre, it certainly was a disaster, but the strongest earthquake of the last 6 years for residents of TAIPEI, was the Easter Sunday earthquake on 31 March 2002 (which caused cranes to fall from the top of TPE 101, which had not been completed at the time).

In fact, the exact measurements, as I recall, were 4.9 in Taipei for 9.21, and 5.0 for 3.31. Much of a muchness, I guess.
