Never used magic before but zoomtext fusion is alright. Fusion is the version of zoomtext that comes with jaws, so if your visual impairment is degenerative or if you just want to learn how to use a screen reader its pretty nice. You can even turn zoomtext off and just use the jaws function if you'd like. If you've never used jaws before, i'd recommend keeping the manual nearby for reference. You can also turn jaws off and just use the zoomtext by itself.

The downside to fusion is that it sometimes makes my computer run REALLY slow. Sometimes i just have to turn the program off entirely and use the crappy windows magnifier.
