Got 4 nights spare. Starting in CM. Can do either loop. I know Rai, Chiang Dao and Pai a bit. I don't know the other places.

 

The other option is just do stuff near CM like sticky waterfall and that short Samoeng Loop.

 

What would you recommend?

Go on the moat loop and once you been around one way, go back around the other way 

Moat?

Big bike or scooter?

The Doi Angkhang loop, as mentioned by PoorSucker, is nice. A night in Chang Dao, two at Angkhang... you could cut across to your 'sticky' falls (assuming you mean Bua Thong) on the way back. You could also do the MHS loop in that kind of time, but a lot more arduous driving/riding. Much better on a bike, esp a scrambler type with hybrid tyres.

I've done both several times. I'd do MHS - Pai, fish cave near MHS, MHS, long neck village, usually elephants on the road down that way, Mae Sariang, cut inland to Doi Inthanon then home down the Mae Wang valley. 

 

Road to Fang is boring, go via Phrao, catch the sticky waterfall on the way down, Tha Ton, teacup temple, go up Doi Lang to the best moo katter place in Northern Thailand. Doi Mae Salong, early in the morning be at the Golden Horse Temple, before 8am, see the monks ride back from collecting alms, Doi Tung, Chiang Saen, Opium museum, and if you can be in Chiang Saen on a Saturday night there's an excellent night market overlooking the river.
