Which would you recommend between gamma and mx?

I’ve been looking for a versatile and durable one piece for a while. Cant decide between the two as I have a few different pieces already and don’t want to be picking one over the other. Have a proton SL, atom SV, squamish, beta SL and a few other bits. I really think I need the gamma most but I love the jade colour-way of the MX and thinking it will be too warm. It’s mostly for walking and Im at the end of summer with the temps in the 15c range and dropping but I still need a jacket for as many use cases as possible.

Would appreciate any recommendations.
