I'm not an experienced hackintosh builder, it was in fact the second pc I built myself based on advice on the forums, before that I usually had Mac Pro's until they got ridiculously expensive. I can't remember the specs of my last hackintosh but it was fast :)
One of the reasons I switched back was that I no longer wanted to tinker with OpenCore & friends, and make a sacrifice to the gods after every OS update :)
The other reasons were that I got tired of the heat, noise and energy consumption, and I started to get weird little issues that I could theoretically solve with reinstalling and/or tinkering with the config. I decided that wasn't for me after all.
I love my Mac Studio (Max, 64GB, 2TB). It's actually silent, even when I push it hard. In terms of GPU I took a slight step back, but I only notice that with some games if I run them on extremely high resolution+settings. In terms of CPU I would say it has similar single-core performance but feels a lot faster because of the fast storage. and the reduced energy usage is immediately noticeable.
Rendering video is comically fast, which is great.
To be honest, it feels like the best Mac I've ever had, and I've had almost all of them in the past.
