Replying to Is it all just marketing

so recently I've been in the market for a new all mountain ski and I've been through reviews and accounts of literally hundreds of different skis. last year I owned 2021/22 black crows Camox as my daily for the season and they were awesome, a bit too much at the start of the season as I was pretty amateur but after like 50 days I had a great cohesion with the skis and found them to be perfect for powder/piste skiing. now in my stupidity I took them to get a base grind far too often and that along with skiing on them early/late season and 100+ days throughout the season, they are completely F*cked and are not going to be skiable for the coming season. The need for a new pair is not so urgent as I wont be able to ski until December and still have my park skis from last season, which didn't get nearly enough attention and as such I will be spending time in the park. however I do want to replace them, so I've boiled it down to these options; 1000's all mountain skis, ON3P Woodsman 108, Vishnu wide +, Sega bighorn 106. (IK some of these are sold out online but i have found people willing to sell each of these skis).

Now here's the problem I'm having; each of these ski brand advertise that they make the best skis, 1000's especially i get 1500 videos a day on IG about their flex and ability and how cool they are etc.. and talking about how different they are from other skis. and there are 100s of reviews online talking up and shit-talking each of these skis - blister and newschoolers reviews both review them all very well but people on IG and whatever point out various flaws etc.

now obviously length and width make big differences in how skis handle, and the camber/rocker makes a big difference.. but besides that is there a big difference between these skis? because the price differences are huge, and they really make it seem like there are big differences, as though they have innovated something crazy, but, for example, 1000s all mountain and Vishnu wide+ are both 106mm width and come in 186cm (this is the size I would get) but do they ski that differently?

p.s. I'm not talking about durability or how skis look, simply how they perform.
