the hv20 is definatly a good camera, its not a bad choice at all, but from the footage ive seen of both the hv20 and gl2 the gl2 still looks much better. Â
i guess it is all personal preferance though.  the hv20 seems to have more "vibrant" colors than a gl2, but that does not mean its better at all, the gl2 can get amazingly unique colors. Â
and as for sharpness, if anything id say lots of sharpness is a bad thing, it just looks bad and amature to me. the gl2 has a softer picture than most 3ccd cameras, and i think thats great.
the hv20 definatly would not be a mistake to buy, but with a nice 3ccd camera like a vx2100, gl2 or dvx you are gonna be able to get just what you want and overall the picture just looks much more profesional in my opinion.
if your not spending like 5000+ on a HD camera, i think its just a waste, its not gonna be real hd, and it seems like more of a gimmick to make people buy their cameras, cause it says HDV on the side so soccer moms are gonna freak and think its so amazing.
