Hugin has gotten me great results in the past. My most popular panorama (https://flic.kr/p/2gw93QX), you can't even find the seams despite being quite wide at 5 × 3 shots. It handled 16-shot panoramas well too (https://flic.kr/p/GLsDNh), even though Flickr won't render those resolutions. I've even used it for focus stacking (https://flic.kr/p/27kMsrX) to keep a narrow depth-of-field on an object that needed 2 focus points to stay sharp.
And with respect to color management and Wayland with the rumored next release of nvidia drivers potentially supporting Wayland that's about the only thing that would stop me from switching on all my machines. I know there is an open issue for working on that in both the Wayland official protocols and wl-roots so hopefully soon.
