This is very subjective dependent on age, weight, skill and the style of board you want.
I have tried a lot of boards over the last five years trying to get a 'go to' short board with some volume for fast beachies.
I am also past it in someways and have a standup and mal but I haven't lost the desire to ride a short board. (Late fifties, 80 Kg, two shoulder ops and could be fitter.)
I have tried everything from Beach Buggy, V3, Uber Driver, Phantom, Black Diamond, Sweet Spot, 3DX, FW Cymatic and Seaside. (All about 35 litres give or take, 34 Lt epoxy and 35-36 PU)
Of those listed I still have the Seaside (great fish, it is fast and will hold as it sucks, a bit hard to paddle in on the fast beachies. I tend to get hung up as the wave starts to suck due to all that volume in the nose and my lack of paddle power)
I was about to buy Puddle Jumper HP and was talked into a Lost Rad Ripper, as the sales rep had one and offered me his board to demo.
It is designed on an 80's shape, just modernised. I have to say I wasn't keen on the the shape, it looked to have too much surface area in the tail to hold in, but it works. It doesn't fit the groveller type but definitley a daily driver, which can go O/H. I ride it as a quad on the beachies, there is good volume but it tends to be in the middle of the board rather than all the way out to the rails or through the tail. The rails and tail are quite refined for the overall size, which I think is the key. It doesn't get hung up and tends to pivot and push you down the wave, something that other modern boards with foam forward of centre (for easy paddling) don't do for me, so it is easier to drop in. I did have to paddle 1/2 - 1 inch further back because of this but that took only the first session to get used to. I have used it as a thruster on slower waves and it feels as good as my old Terry Fitzgerald Hot Buttered Thruster from the 80's, even looks a little bit like it

maybe that's why I like it, something similar to what I learnt on.
(I have no affiliation with brands or shops and it has been an expensive but enjoyable journey)
