I have a 5 and a Patriot in an XC build, which I suppose is loosely equivalent to the Alpine..? I choose the Patriot for anything that looks like being big – it’s too good of an opportunity to miss.
Climbing on the 5 is much nicer, but descending on the Patriot is so excellent that it easily cancels out the climbing.. If all I wanted to do was climb well I’d use a road bike 🙂
The thing that limits gnar-ness on the 5 really is the head angle and top tube length. Absolutely not an issue in normal riding really but when it gets steep and technical the Patriot is just better. And then on big rocky stuff it’s the extra stiffness, bigger tyres, wider bar, shorter stem, better brakes etc that I really appreciate.
