How long ago did you try? I built my first one in mid 2016 using the newest chipset/CPU (at the time) and it has been quite trouble free and reliable. Of course, there was a bit of tinkering required in the beginning, but once everything was setup there was no longer any tinkering required.
In my limited experience, I've found systems with UEFI to be pretty easy to get up and running reliably. I experimented briefly with an old, non-UEFI system and it was indeed considerably more complicated. However, I found a guide written by another user of that same motherboard, followed it closely, and it turned out to be as solid as any Mac would be. Again, after following the guide, no tinkering was required. What I learned was, stay as close hardware-wise to what Apple uses in their systems as possible and look for and use systems with UEFI.
Even OS updates have proven to be pretty painless. I've just made sure to upgrade to the latest versions of Clover prior to upgrading and everything just worked and I have been able to perform every upgrade directly over the Mac App Store within a day or two of release (I have to wait for Nvidia to release their web drivers).
I was so impressed with how well my system ran that I recently took a chance and purchased a used Dell laptop. With a bit of assistance from a very knowledgeable member of the hackintosh community, We got everything(!) working perfectly in a day or two. Again, I have not had to do an ounce of tinkering since the beginning and updates have been as simple as any real Mac. I have found it an absolute pleasure using this laptop especially compared to the ancient 2008 MacBook5,1 it replaced. The $190 I spent on that laptop might be the best $190 I ever spent.
