Ive had a custom 20 VT. Good little round, but nothing special. I built it expecting a lot less recoil than my 204R to watch hits on ground squirrels up close, but that wasn't the case. The 20 VT has more recoil than most might think. Sold it because fireball brass is expensive, hard to find, and usually not very good quality. Made some brass from 223, but that was a lot more work than I wanted to deal with. So off she went.
For ultimate low recoil, I have a 20 Ackley Hornet. Can watch all the shots, but nowhere near the speed and power of my 204R. So that's the trade off.
I recently built a 20 TAC so I can use 223 brass. Accurate and fast, but not 'better' than my 204R. Similar recoil and speeds, just that 223 brass is more available and there are more brand options so it's more convenient.
Regardless of what anyone thinks of the 204 Ruger, it is one hell of a round that will leave the 223 in the dust with any similar weight bullet. Trying to claim a 223 is a similar ballistic match to the 204 Ruger is like trying tell folks Tyrannosaurus Rex still roams the earth. It just isn't true. As far as accuracy? I would pit my custom 204 Ruger against any other wildcat 20 cal rifle out there and I'm sure it would give them on hell of a run for their money at 300 to 600 yards.
One thing to remember is that even tho the 204 Ruger may not be as exciting and unique as it was when it very first hit the market, it is still the one and only cartridge that sparked the 20 cal craze. I absolutely love my 20 cal rifles and I know I probably wouldn't have paid attention to 20 cals if it wasn't for the fast success of the 204 Ruger. I like 20 cals so much that i dont even own a 17 or 22 cal center fire rifle. So I gotta say my hats off to Hornady and Ruger for designing such an excellent cartridge. I know I'm hooked on 20 cal and probably always will be. I guess my way of showing respect to the cartridge that started it all is to make sure I always have a 204 Ruger tucked away in my safe.
