From reliable industry sources, one of which we can call "Ola", I know that Simmer boards in the last years have held up really well. Maybe best quality in the production board industry these days? The Simmer boards are highly rated here, well it is a Swedish brand after all..., and the recent versions I have tried (Flywave, Cortex) I liked a lot.
I can also personally vouch for Flikka's quality. And have no affiliation with them. My local spot is very unforgiving on gear, rocks only, and combined with travel damages (flights...) I got fed up with constant repairs and ordered my first Flikka board in 2014, a custom compact 84 L shape. I've had five Flikka boards - 102 compact allwave with foilbox in regular light construction (still own this), 95 compact wave in regular light, 88 quad custom in regular construction (own) 84 custom in dyneema regular construction, 83 quad in regular construction.
Over all these years I have done one (1) repair. This was after sailing OVER a big rock at my local break.

Considering the amount of abuse they have seen, above all the 95, 84 and 83, this really is a testament to the Flikka quality. I actually lost my 84 in a strong gust on the beach, rocks only. It tumbled 5-6 times end-over-end, the horror!, only to get stopped by a fence (!). No repairs. I have a good friend that is VERY hard on gear. Only three things has survived his abuse over the years - his two Flikka boards (with a couple of repairs, though) and a AL 360 carbon boom.
I personally like the Flikka Compact shape quite a lot for onshore in lighter winds and think that Luca and the team have improved their waveboards a fair bit the last couple of years, not least through the input from some very skilled team riders. My current quad 88 custom is better in every single aspect than my previous quad 83, which I still liked a lot. I have also given the Flikka Thruster a go, with a faster rocker, and could easily see this as my onshore freewave board.
If anyone happens to have the time and patience to read a bit more about my Flikka 88 and 102..., look here -
