Love my QR. Pulling stuff off with oily hands *****. Same with having your sockets or extensions pop off your ratchet during removal which happens constantly in the rust belt. Remember, its not just quick release, its locking. The Snap-Ons have been my most used ratchets since they introduced them.
If the button is going to "interfere" then chances are a regular ratchet is going to barely work too and there is a better tool (through socket or ratcheting wrench). We're talking about a mere 1/8th of an inch here, nothing game changing and with Snap-Ons the direction lever is already sticking out roughly the same distance anyway.
QR also have the added benefit of using the button like the back of a palm control ratchet, so that you're applying resistance to a loose fastener preventing the back-drag from spinning the bolt/nut the wrong way.
If you really want a flush design Nepros 90 tooth feel very similar to dual 80s and have a flat button. Unfortunately they also cost more.
