No harm in checking out the trial. Plus it's 25 bucks. That's a no risk scenario to a ultra low risk scenario.
I have Affinity Designer and Photo. The workflow in Photo is a mess IMO. Designer is closer to to Illustrator than Photo is to Photoshop. The "Personas" in Designer, at least the two main ones (Vector and Pixel) makes sense. In Photo, it kind of doesn't. It seems rather superfluous.
There is no batch editing with Affinity Photo in the way anyone serious is used to in LR or Bridge. Also, LR is still the fastest. Adobe hate or not, people need to live with it.
Plugin support is still meh with Photo even though they emulated PS plugin support.
Adobe is moving up a tier and is catered to professionals with the CC products. They offer casual online only products and Elements for everything else. People hate them for that, but guess what? Every other professional grade product in almost every industry has the same model.
The curt people telling Adobe to *expletive off are for people that aren't interested in what Adobe offers and Affinity doesn't.
Can I work with Affinity as a professional? Yes, but I don't want to.
