Of course the Hunter (or any other well flown fighter) would use less fuel when landing. I would never say otherwise.
However there is a huge but at the end of the sortie.
And that but is that you can join the ship or a circuit to land vertically with 2 mins hover fuel remaining, use half of it and think how boring it was to sit in the hover for 30 secs doing nothing. The twitch when you must trap or do a reasonable conventional approach (especially when the vis is poor) is just not there if you can VL (anywhere).
Quite a lot of the fuel tankage difference between the F-35B and the other versions will be needed to give sensible landing reserves - although I don't expect that to be understood by many.
