Water conditions make all the difference.
If there are surfable waves that you can get to, the surfboard will provide the most fun on the wave, and maybe it's no big deal if you have to walk back upwind every now and then, as long as you get your wave count.
If there are waves but it's dead onshore and light, it's unlikely you'll get in a position where to ride a wave, so you might as well be on a lightwind TT / door and ride the shallows where no surfboard could go due to the fins.
If there are no waves, and it's deep enough, no weeds, foil.
I've spent quite a few years playing with light wind TT, finless, negative radius, like Litewave's Wing, or Spleene doors, although with more reasonable sizing (about 140x40), which made them not bulky or awkward under foot. On some conditions, they were the absolute tool for the job and would outdo all other options (TT, surfboard, skim). No fins, no drag, no catch on the shallows, and you can tap into some ground effect to provide a significant lift, use the surges by the beach to give you a few extra knots, and use the glide and consequent rail length to crank upwind.
One example: shallow, weeds,... knifing through it!
