It's good to support creators if you like what they're doing. I've supported Zishy in the past because they do high quality tasteful clothed/teasing photos of women who look like real women (not that there's anything wrong with bimbos/plastic surgery). If you appreciate what someone is doing, monetary support isn't unusual at all.
The only porn I would pay for is something bespoke that I had to specifically request be made.
I've found the quality goes up with paid porn, ethical porn is easier to get, and is also less objectifying.
For example, there's a bit on the Upper Floor between Stefanos (the dom and main host) and Penny Barber (one of the subs in that session). Penny noticed that Stefanos was wearing french cuffs, which she really likes. The next time she was on, Stefanos was sure to wear french cuffs again. It didn't enhance the show's primary purpose, which is titillation. It was simply a sweet gesture.
Now, many Upper Floor scenes are available in part on PornHub and the like, but this is one interaction that's likely cut. Even if it's left in, you might not be able to piece the two together unless you watched the series in order, which would be hard to do on tube sites.
Kink.com in general has pre and post interviews on almost all their content, which you don't always see on PornHub. These often give personal insights into the people and the industry that may be cut out.
AdultTime and Bree Mills are also doing some interesting work putting more women into production roles behind the camera, and stressing consent.
Finally, there's a list of sites like crashpadseries.com that are also stressing ethical porn, and they tend to deliberately keep their stuff off of tube sites.
If I’m going invest 3 hours into a film or a series of films then I want a plot to follow
