I will flip your 1 and 2, otherwise I agree.
1. NSMB U
2. NSMB Wii
3. NSMB
4. NSMB 2
The DS one might be the original, but the level design really isn't all that good. I also thought the mega mushroom was a stupid idea.
The coin gimmick in 2 never worked for me, and the game was just way too easy.
The two home console versions are the good ones, with the one for Wii U having the most consistent and creative level design.
