Switched back to Android gesture navigation a few weeks ago and I still think it sucks. Sometimes trying to access content on the edge of the screen is annoying (mostly websites that aren't considering this).
But I think my biggest annoyance is my brain instinctively thinks the other side of the screen should be "forward". Probably learnt from how the app switcher works.
Eg if back exits the app forward should reopen it. If back goes back a view forward should go return you to that view.
