Difference between Choc and low profile keycaps?

I'm a big fan of choc keys. But I think their spacing is different than traditional keycaps, so they're not interchangeable ?

Recently there was somebody advertising a board that looked perfect for me, except they were using normal keycaps, but offered a low profile version as well. How do those compare to choc keys?

I'm really looking for minimal travel of fingers, and cutting down the size of the board, so ideally having them choc size would be great.
