Real quick, the switchblade could not hold a candle next to the sentinel at descending. Most bikes in this category are pretty similar in geo, travel, and price. Unless you look at the new HP trail bikes, those are a totally different animal and require a separate conversation. Is price a factor? Do you care about difficulty of maintenance? What types of riding to you spend the most time doing? What kind of trails are they? Do you care about weight? What kind of climbing do you have to do, is it technical or smooth? I dont see the point...

There are some incredible deals going right now on previous gen Norco Sights and Marin Alpine Trails.

I love my Stumpy EVO I have a Zeb on it and I switch between a deluxe air and deluxe coil depending if I'm going to do some lift served stuff for a whole weekend. The head angle and chain stay adjustments actually make a huge difference, that along with tires this thing works awesome for me from local XC after work rides to big Pisgah rides to a weekend at Snowshoe/Windrock. I'm on the alloy frame and I plan to keep this indefinitely and if it breaks ill probably get the new one if they have an alloy as...

Also on a 2021 Sentinel and I'll probably ride it til it dies. More options for you are the Atherton 150, RAAW Madonna (Jibb might fit the all mountain category better), and Forbidden Druid. I did demo a We Are One Arrival 150 and it's the only bike I've tried that has tempted me towards a new frame. That bike was a ton of fun to ride

Why not another sentinel if you liked it? Could ride the current one till it actually breaks and get a crash replacement frame. Spires/Patrols are also less playful than the sentinel but still have a pretty decent pedaling platform/playfulness if you want to try something with more travel.

Orbea Rallon always gets very good reviews, pick a Santa Cruz in your category also. Nothing will be miles better than a Sentinel which is already such a solid bike so maybe look for extra features like in frame storage etc I'm considering the new Rocky Altitude, but I'd say it's more race bike than all mountain

The new Hightower should be considered too. It's very solidly in that category with a slight tilt towards descents. I'd consider a V2 Druid too. 130mm travel only but definitely rides as if it had more. In this category I think tires can make a huge difference and can tilt any bike more towards trail or enduro depending on what rubber is mounted up. Jeffsy could be a contender too at a cheaper price point if that is a consideration. You could do a Revel Rail also which behaves more as an all mountain bike. Lot's to choose from for...
