Not switching, since a low bar squat is still stronger, so it makes me sense for me for as a competition squat. But, my LB is very hip dominant, so for a lot of my training volume, I think a squat that's shifts that a little bit more to the quads makes sense.
That said, my HB isn't some "Oly ATG" HB. I'm using the same stance as my LB, and hitting about the same depth. The big differences are I'm more upright with a HB, and I have a bit more forward knee travel. So they're not radically different squats.
