Honestly, I love Sketch—The Invision Craft plugin has really done some crazy stuff to extend that love. However, I'm not attached to it that I won't try something new.. just slightly hesitant after spending so much time utilising Sketch, designing shared symbol libraries for the UX and visual design teams to use, amongst other things.

AD looks brill, in fact it looks like Photoshop.. which is something I still have nightmares about. It's great to hear they're coming out with a rival to InD, perhaps the only Adobe software I still use (and still enjoy).

Sketch is far from buggy now, it's usually plugins that cause issues.. I do however miss the extra control on things like typography which I understand AD solves. Does it have a light UI by any chance?
