As small as is usable is better with U locks. Larger ones can be jacked open easily. Locking the wheel like this means the frame is secure. It's topologically impossible to get the frame without destroying the rear wheel.
They aren't better if you can't fit them around your frame lol, that said, yeah it's ideal to use one they can't get a jack under.
But there is no practical benefit to including the frame because locking the wheel like this also secures the frame.
How does that secure the frame?
The wheel is much bigger than the triangle in the frame you would have to pull it through. You would have to cut the rim and tire, or theoretically bend and collapse the wheel, to get the frame away. And then you have a frame without a wheel to try to sell.
Before a thief destroys its value like that, they would get an angle grinder to the lock. Or more likely, move on and look for another bike.
~~They just take the wheel off, this does not secure the frame. The u lock needs to go around the frame.~~
Ok, I get it now, disregard. Still seems like locking the frame would be a little more secure but I guess this would work too.
When the lock secures the rear wheel within the rear triangle, you can't remove the frame without destroying the rear wheel. Try it at home. It's called the Sheldon Brown method.
That's topologically impossible
I see what you mean now, Frostbiker explained it.
