I had a 2020.
Great bike. Light (lighter than my Ti road bike), agile and well made, plus as others have mentioned, Santa Cruz have a good reputation for looking after their customers.
I don’t have a bad word to say about mine. I only ended up selling it fund our house refurbishment. The only downside which is purely subjective is that it is a little heavy looking around the headtube junction with the downtube where it is oversized compared to some more traditional looking headtubes, but that would really be nitpicking and I guess it adds vital strength. I am also not a big fan of dropped seat stays below the intersection of the top tube, but again I think that adds a little comfort.
I ran both 700c and 650b wheels and without a doubt I would stick to 700c. It felt sluggish on 650b wheels.
Now, the real question here is whether I would replace a hardtail with a gravel bike. The clear answer is no. Gravel bikes definitely have their place as road/off-road hybrids, but for pure off-roading a mountain bike wins every time.
