I’m feeling this way about my Yelli Screamy at the moment. It rocked at BikePark Wales, it does local XC and ST riding perfectly well (any limit on speed is me not the bike, same with technical riding), it’s fun, stable, fast and flickable too. It makes a nippy single speed, I think the short chainstays help on attacking climbs stood up.
I’ve been through half a dozen frames over the last couple of years and the process now seems to be reducing back to just one.
Perhaps I’ll get a second wheel set so I can quickly switch between light XC and heavier trail set ups, that’s still a fraction of the cost of a second bike.
If I ever “must have” an FS, I’ll rent one.
