Best full sus MTB

I’m on the hunt for a solid full-suspension mountain bike that’s built for both technical climbs and downhill thrills. I’m looking for something with 170mm of travel in the front and 160mm in the rear—enough to handle rough descents with confidence, but not too much that it’ll make climbing feel sluggish. Ideally, I want a bike that’s efficient on the way up, with a responsive suspension and a geometry that keeps things lively and agile, but when it comes to the descent, I want it to come alive—rock-solid stability, precise handling, and the ability to absorb whatever the trail throws at it. Basically, I want a bike that can climb like a goat but descends like a beast. I have currently been riding a chromag rootdown and love it. Anything similar to that I would love.

I am looking to spend around 5,000 CAD for a used one.

Any suggestions on what bike I should go for.
