I've tried both and daily-drive qutebrowser; they're not really in the same category.
Qutebrowser's main deal is the interface for interacting with it; the underlying browser engine is stock qtwebengine6, which is Chromium-based.
Dillo has its own browser engine, but a pretty minimal one that is more like a browser engine from a couple decades ago than a current one. It's mostly gonna be able to do small web sites, not Web 2.0 or anything with modern features. It probably won't be your only browser if you use it, but it is a fun lightweight one to play around with.
