I'd say they look to be producing about the same results. And let's be honest, 3 MOA for 10 rounds is reality with kit even more expensive than these rifles.
I did a review of the WK in 2018 and posted my results here:

The groups approaching 2 MOA were left over handloads from my time competing in Service Rifle.
I've been able to get 2moa with Federal 55 grain bulk at 40c a round, 10round groups pushed it between 2 and 3 moa.
I'll take my WK180C out and see what I can do with the Barnaul 55gr stuff I have then get some pics
