Can't say I have a single favorite or favorite type of .22LR. I have everything in the poll except for a revolver. Need to fix that.
I guess the Ruger Mk II target pistol is the most fun, right now.
I'm also learning to shoot long range .22LR with an accurate match grade bolt gun. Wind doping at 200 yards and beyond is a very sobering, humbling reality check even with a sub MOA rifle shooting match ammo.
I also enjoy helping my grandchildren learn to shoot with a simple single-shot bolt gun that my dad bought used and gave to me when I was about 12 years old.
I have tube fed lever and semi-automatic .22LR rifles and a couple magazine fed ones that I pull out of the safe from time to time. Just depends on the mood I'm in. My ancient pump .22LR is in need of repair. The extractor needs replacing.
What I can say is don't limit yourself to one rimfire type. They are all fun, each in its own distinctive way.
