i think is is the 4 player stuff is awsome and harder levels and yoshi

Right...
 
Having played both I would say yes it's better.

Definitely. Though the two may share many similarities, the improvements and additions to Wii game make it much better than its handheld counterpart.

Sigh. Troll. Posted another topic asking whether RE4 was better than RE5.

for sure, 4 player madness FTW

Well, the DS version can be thought of as the travel size version of the game.

No. I think the DS one is better.

For me this one is way better. The DS one seems lacking in comparison. Though I will admit, I like that there's more to do with the special coins on the DS version.

The DS version is better.  I hate controlling my character with the wiimote held sideways because it feels very awkward.  Also, the lack of retro gamepad support killed this game for me.  IF........and a big if we could play this game (including the propeller suit) with the retro gamepad only then would I say yes this game is better than the DS version.

New Super Mario Bros for the DS is better. Simply because it was original. I know this sounds horrible, and Super Mario Bros Wii has a great level design throughout, but NSMB on the DS just felt fresh when it came out, playing this is more like having a stain on your T-Shirt and hiding it up with your Jumper.

Sometimes when I play the DS game... I accidentally shake the DS because I want to get that extra hover jump...

It most definitely is, but I only wish it came out on DS. It would have made more sense, as the reason I played so much of the first New Super Mario Bros. was because it was a great portable game that I could play anywhere.

I personally prefer the DS version. I mean it was just more shocking at the time that you could play a new sidescrolling Mario game, with the Wii game it just seems like Novelty. Don't get me wrong it was fun, but more like a 3/5 for me.
