Honestly didn’t know they even made hard tails until I saw this thread 🙂
Only experience so far with XC bikes is my Cube Reaction GTC Race (Lightweight/fast/capable). I did a 45 mile ride with lots of climbing and some rocky descents on it and it performed great!
The only reason I sold it was because it was replaced with a Scott Spark RC. I’ve done all sorts on this. Took me a while to gel with it, but once I did I started loving long epics on it!
The twinloc remote is really useful and I have it in the middle setting most of the time (lock out for road sections and fully unlock for more technical descents). The only thing I can fault it on is on quite steep climbs, the front can wander if you’re not careful (slackish seat tube on an XL).
I really think unless you’re winching up and bombing down technical/steep descents all day, a sorted 100/120mm bike would be suitable for full days out in the hills.
My missus rides a 2016/17 Trek Top Fuel 9.8 and she loves that too! A lot of people dismiss them for being too steep in the HA, but it really doesn’t hold her back on the descents. I’d like to try one in my size… then again, I’d love to try a lot of the current crop of XC bikes.
