Very strange choices...
Not when you view them in the context of this being the umpteenth thread asking for everyone's favorites. I could parrot the typical best-of list and say Gate of Thunder, Lords of Thunder, Ys, Beyond Shadowgate, Dungeon Explorer 2, Legend of Xanadu, Bonk, etc., but what's the point? Other's will mention 'em anyway, and people need to branch out and try something different, even if it's not an flawless A+ title.
I got the implication that this is what OP was asking for - what we thought was the best on the system. I'd give some very different answers if it was personal favorites. I think there is a point in highlighting the best the console has to offer though especially if they are new to the library. Gives a good starting point - see which games get mentioned the most and start with those.
I think for personal favorites I'd have to go with:
Genji Tsuushin Agedema
Bazaru de Gozaru
Mad Stalker Full Metal Force
Kaze Kiri
Horror Story
some runners-up: Cho aniki, Mizubaku Daibouken , Kabuki Ittou Ryoudan
