Regarding the reproduction 52s...I bought two of these new in 1997. I haven't done a side-by-side accuracy comparsion, but I think they'll outshoot the Ruger bolt-actions by at least a little bit and the Rugers shoot well. However, I'm not up on prices, but I'd guess these reproductions are failry expensive today, more than most would want to spend on a .22.
All three of my Model 52 “R” reissue sporters are 1.25 MOA 5 shot group rifles at 100 yards with SK Standard Plus.
Price wise, the Winchester marked rifles are selling for around $1000 as new in the box, with excellent condition with no box examples selling for around $800. You’ll see them listed for $200-$250 more but those rifles don’t sell, or at least don’t sell quickly.
The Browning marked examples can bring a little more, as do examples with nicer wood.

Ruger 77/22s have a reputation for spotty accuracy with some of them being around 3 MOA. Mine was.
The first step generally is to buy an inexpensive shim kit and shim the two piece bolt for minimum head space and that will almost always provide some improvement in accuracy.
The next most common step is to replace the trigger with one of the three or four aftermarket trigger kits out there. They all work well, with some range in pull weights between them.
Last is the bedding. Ruger designed both the M77 and the 77/22 with flat bottom actions that theoretically will bed properly in the same horizontal plane, making it amenable to dropping into a machine cut stock.
It doesn’t always work that way with the 77/22. The 77/22 comes from the factory bedded with some fore end pressure on the barrel and that can vary over time and humidity, and enough to interfere with the bedding of the action.
When I attempted to free float the barrel I quickly discovered the more wood I sanded from the bottom of the fore end the more the front of the action settled into the action, so bedding it was necessary.
The 77/22 is however very easy to bed as it just needs support at four points: under the barrel block; under the tang; and under the two flats behind the magazine well.
Those changes improved the accuracy from around 3 MOA due to significant vertical stringing to around 1.5 MOA with significantly less vertical stringing.
