Seconded. It's just different enough from Illustrator to be unsettling for the first few days, but the core of it is immediately and very obviously excellent. I persevered (it's vastly less money) and I'm very pleased I did. It's significantly smoother and faster in daily use than Illustrator (at least on my machine) and that counts for a lot for me. Updates are thoughtful and contain useful features. There's very little now that I actually have to work around and some parts of it are just intrinsically better - snapping candidates, for example.

I'm really liking it myself. Unfortunately I've got hundreds of hours wrapped up in making maps that I periodically update, and there's no good path to move them from Illustrator to Designer. PDFs move, but then every path comes over weird... And without the layers and groupings that are otherwise so helpful.

You should be able to open Illustrator files directly in Affinity Designer.
