The Affinity products on Mac are some of the cleanest, polished, reasonably easy to use, responsive, and stable pieces of commercial image software I've used in years. Very impressed with what they've done so far.
They also have a good offer on at the moment. They’ve released V2 and are offering all 3 apps on all supported formats for a single payment. Personally I only use Designer so didn’t partake, but even that is discounted a little.
