You can also consider sway, a nearly drop-in replacement for i3 (with gaps support), but based on Wayland. While I don't want to start a flamewar between X.org fans and everything else fans, one big feature of it is that VSync *just works*, without having to drop into arcane configuration details - a game changer for me, personally.
