While I'm not discounting your opinions, esp. since I have not tested one myself, I must point out that testing at 1280x1024 isn't always a good indicator of 2D quality, except at 1280x1024. I find a lot of cards get much worse at 1600x1200. Luckily the Matrox and ATI Radeon cards I have tested do very well at 1600x1200x75. The Voodoo 3 does not (at least the one I had).
So, before declaring the 2D good, check at higher resolutions, with a decent refresh rate. (It may very well turn out that it IS good, considering the other brands of G3s do well at those higher resolutions. Or not.)
By the way, 1280x1024 is an "incorrect" resolution. All properly formatted images (eg. out of a digicam or on the web) will be incorrectly displayed, since the 1280x1024 resolution is 5:4, in contrast to the 4:3 aspect ratio of your monitor. Other resolutions like 800x600, 1024x768, 1280x960, 1400x1050, & 1600x1200 all are 4:3 and thus will display images correctly.
