If you're going to tile, I'd make sure they are in the middle of a tile
run at least 4" above the worktops to the bottom of a socket.

I like 6" to the bottom of the box so the first tile sits nicely under
the socket, then 18" above that to the wall units.

That would also be fine, but of course depends on the size of the tiles.

Personally I prefer them higher than that, so they are up out of the way
of worktop clutter. but as long as the person using them is happy I
don't think it matters
