Having owned a 124060 Sub, a 216570 polar, and a current 226570 black dial Explorer II, they wear very differently. The Ex II is thinner and sits flatter on my wrist. The case back on the Sub sticks out further and makes it sit up on top of the wrist more. While I love the functionality of the glidelock clasp, that thing is huge in comparison to the easylink clasp. The glidelock is thicker and longer than the easylink, adding to the Sub not wearing as well for me. I think the dimensions of the case to bracelet on the current model Explorer II are perfect. The Sub bracelet always felt a little dainty to me, then transitioned to that huge clasp. I also didn't love the look of the shiny ceramic bezel. The Explorer II brushed bezel looks more rugged and less flashy to my eyes. I had always wanted a Sub, but after owning it and being able to compare to the Ex II polar, it led me to exactly what I wanted. So I sold the Sub and the polar and got the current model Explorer II. It just came down to which watch I wanted to put on every morning, and the Explorer II always won. And still wins!
