it improved over time, and nowadays if you go and get the OS truetype implementation, it's actually pretty damned good (what's it called, opentype IIRC?), but when it came out TT fonts did look bloody awful... on the screen. It worked fine for print output, but I still prefer using ATM fonts on Warp, despite the fact that TT works very well now. Not least because they work sooooo much better in PDFs.
