I find Adobe to be a bit like Apple, I hate being stuck in the ecosystem but the alternatives just aren't as good for me so always end up back at Lightroom, particularly as I do some editing on my iPad and LR is still by far the best tool there.
That said, I have just downloaded and tried Luminar 3, and although it isn't LR, will take a bit of getting used to and the whole 'AI' thing annoys me I think I could live with it as the output seems fine, especially as with the current sale price and a code it is only £45. I'll DL a trial of Capture One too and see how that works.
I probably only use LR twice a month max so IF the prices are doubled I think I could make do, it would also be nice to only have one subscription of online storage (iCloud).
