Out of the box, a Henry octagon barrel will be the most accurate of the 3 mentioned. The Marlin 60 would be second, and the 10/22 would be last.

I own a 10/22, Marlin 60 and a Henry Golden Boy. The 10/22 is fun to go through a lot of ammo with quickly. It is also the versatile in the fact that there's almost any accessory out there that you could want to bolt onto it, but to make it a better shooter then the Marlin or the Henry, you'll need to swap out the barrel with an aftermarket one.
I've owned a couple of different Marlins and I prefer shooting them over the 10/22. The Marlins seem to have less failures with the cheap bulk ammo. There's not a lot of aftermarket support though to convert a Marlin 60 into a AR15 or AK47 look alike.
My most recent purchase is the Henry Golden Boy. This is my favorite 22 rifle so far. It will shoot 22lr and 22shorts. The 22shorts out of this gun are quieter then an air rifle. This was a blast to shoot last weekend.
I just recently ordered a Spee-D-Loader for reloading tube magazines. it holds 120rds of 22lr. This will allow me to shoot just as much as a 10/22 with a couple of aftermarket mags and it's faster to reload the spee-d-loader then a 30rd mag for a 10/22.

I liked the Golden Boy so much, that I'm getting another Henry lever action this weekend. It's the round barreled model and needs a bit of TLC, but I can't complain about the price!!
