I have used Ryot for a while. It is nice and has a lot of features. It has documentation, which is really nice.
I am using Media Tracker because it has most of the features I need and it's very fast. I wish it had genre sections like Ryot though. It looks like someone created an issue for it at least. Might go back to Ryot eventually, but we'll see. Luckily Ryot has a Media Tracker import option.
I was wondering why everyone kept talking about Media Tracker being fast. I finally installed RYOT, and wow is it slow, and resource intensive. It's using more than 20% of the CPU on my NAS when it isn't even open!
