1. 3x3 speed
2. 5x5 speed I like the way my 5x5 feels and it's doesn't take very long to solve
3. 3x3 BLD Almost tied with 5x5 speed, but after a while I get tired of memo. I like it a lot more now that I'm faster.
4. Pyraminx Doesn't take long to solve, makes me feel pro because I'm sub 10 at something other than 2x2
5. 4x4 speed My x-cube 4 is pretty stiff, so my hands get tired easily.
6. 2x2 speed I only know CLL, and I hate building the first layer
7. Square 1 I almost never solve it, because the stickers suck on mine, but I hope to get a new one, because I like it.
8. 7x7 speed Takes too long and my 7x7 locks up a lot
9. 6x6 speed The cube itself sucks
10. 3x3 one handed lol
I forgot Megaminx, but I'm to lazy to edit the list. I'll say it'll be after 4x4 speed.
