I switched from Adobe to Affinity a few years back. The interfaces of the Affinity apps are way better and the apps work much smoother and even have fully fledged iPad versions. There was not really a learning curve for me other than googling very specific stuff every now and then.

The biggest issue is probably that there’s no feature parity between the Affinity and Adobe apps yet. So every once in a while a feature might just be missing.

I’d suggest to just check out the trial versions or even buy the apps right away if your financial situation allows it.
