Spin Planet is heavier, midsole foam is not as performance-oriented. I think it has a lot of recycled content which is a good thing, but again, it's not really a performance or racing shoe. With the Spin Ultra here you should be able to charge through the terrain you mention no problem, with a bit more agility and feel than the Spin Planet. The fit of the Spin Ultra is a bit more dialed though, so be aware of that. I found Spin Planet a bit wide / accomodating.
I didn't get along with the fit of the previous Spin Ultra. It really squeezed my forefoot too much no matter what I tried. For me, the upper on this one is much better.
That's because those are not even running shoes, but for hiking. The Rapid LT is an approach-shoe. I mean coming from Salomon, everything is an upgrade, I guess, but that is a weird comparison.
That being said, Scarpa arguably makes some of the best mountaineering boots in the world, but all of their trailrunners absolutely suck, except maybe the Spin Ultra 2, which was halfway decent.
There's absolutely no running shoe that really works on wet, slippery rocks, you'd need crampons for that or whatever. I just did a 32k/2500m mountain crossing recently in heavy rain, and it was absolutely abysmal, although I'm an avid runner and mountaineer. It took me over an hour more than usual and I really reached my limit several times during that run.
For everything else there are special rubber compounds that are more sticky than regular running shoes (like Vibram Megagrip). A lot of performative trail running shoes (Scarpa Spin Ultra 2, Hoka Tecton X, Hoka Mafate X, Dynafit Ultra Pro 2) use this very sole, others use a similar system (La Sportiva Prodigio Pro). They perform very well in a dry alpine environment, but have, as I said before, their limits in rain and mud. Also the additional grip adds to the already high abrasion, which means your soles will disintegrate even faster than regular runners. Not as bad as the early Salomon Speedcrosses, but don't expect to do 1000k in these boots.
Edit: spelling
La Sportiva Prodigio Pro or Scarpa Spin Ultra 2. Depends on if you have a Scarpa foot or a La Sportiva foot. I’ve used both and the La Sportiva worked better for my feet.
Scarpa. Got a pair of Scarpa Spin Ultras last year...they're def in my top 3 fav shoes of all time for mountain running. Check all the boxes with 0 complaints....think they were on sale for like 70 bucks at the time cuz no one in the US buys em. Wish I bought like 5 pairs...can't find em anymore
More generous, this is the second/third iteration at this type of shoe, and they are closer to nailing that "all mountain" trail shoe. This shoe is way more runable than Bushidos, I have both.

Scarpa Spin Ultra 2. They aren’t the widest in the toe box but the material and upper construction wraps the foot in a way that doesn’t cause issues for me. I love the Kjerag 02 for everything g except the pointy toe box, the just cause too many blisters. The Scarpas solved that for me.
