For me it depends.
I was down at a topless resort and for the most part, bathing suits were not much more than triangles, and few wore tops. But a few woman would rock the tiny suit with the landing strip coming up about 1 to 2 inches over the top of the bikini bottoms. It was surprisingly a real turn on for me.
So for bikini wearers, tease that landing strip, be brave and let it come over the top of your bikini a couple of inches.
I love eating pussy and smooth lips and clits that are slick from her juices are the best - for eating pussy, give me smooth and bare (no stubble!).
But for nude beaches, there's something about a full bush (think never been shaved or last shaved at least a year ago). it takes me back to the 70's when I was a young teenager and went to a nude swimming hole down in Austin where all the woman were rocking full bushes (otherwise known as the fur bikini).
So the 14 year old in me votes for full, never shaved bush.
