Tennis games: World Court Tennis is quite good, even if the English localization is a hilarious disaster -- among the worst I've seen. The underlying engine is excellent, though, as it's basically a carbon copy of the terrific Famicom release Family Tennis. It'd be nice if the original Japanese release, Pro Tennis: World Court, got a fresh fan translation.
I've heard great things about Final Match Tennis but have only played it briefly. Davis Cup Tennis wasn't released in Japan, and anyway it's much better on the Genesis/Mega Drive -- the TG-16 version is stiff and controls poorly. Not sure if I've played Power Tennis.
Hit the Ice may be the best version of the three home console ports; it's certainly better than the horrible SNES port, but the Genesis version has some nice perks like a password system (the TG-16 game goes on far too long).
I found Sonic Spike Volleyball (aka World Beach Volley) very frustrating.
