Don't feel like reading the thread.
1) Is the game really good?
1.1) Why?
2) Which is the better version?
2.1) Why?
1) Yes. I don't know if you mean "really good" or are asking if the game is in fact good. If you like isometric games and a challenge, it's really (or maybe REALLY REALLY) good. I think objectively speaking it's good once you get past the first 1.5 hours.
1.1) It's a shooter with exploration. If you enjoy semi-original IPs, chained explosions, grappling hooks, frantic running around, and switch-type puzzles, you will like this game. There are problems: you can't orient yourself at an angle when you stop running, so the grappling hook is irritating to use at an angle; jumping to moving platforms is hard to get used to as there's no shadow. Still, it's really entertaining and really satisfying, at least in small bursts, which is how I've been playing it.
The art and music are fantastic, among the very best on the GBA. Some of it's pretty impressive -- HUD splatter, fog, day/night shifts (!) -- though shadows aren't done as well as in Racing Gears Advance.
Most of the common complaints about it (regenerating enemies, too many enemies, isometric controls, stop-to-shoot) go away pretty quickly. I think most of the naysayers gave up pretty quickly.
2) Whichever is on your preferred platform. GBA Micro is one of my favorite systems because of its inputs, so I enjoyed it much more than my DSfat. Haven't played it on Lite (though I'm looking forward to it -- I have both versions). The map thing isn't really much of an issue, though I guess it's useful to have it always present.
Anyway, so far, I haven't found it to be that difficult (though I hear the last boss is very tough). I've only been forced to scramble for a save point due to infection three or four times after the first two hours, and only the second boss has put up much of a fight (though I was being stupid, too). I'm looking forward to hard mode, though I sure wish I could transfer my progress to the DS version so when I get a Lite I can play through it on hard. Ah well.
