I had a IZH-43 side-by-side in 20 gauge. I probably only ran about 300 rounds through it before I traded it off. The LOP was so short it would slap the shit out of my cheek. I've never owned a 20 gauge that kicked more than that gun. I loaned it out a couple times to guests at the skeet range with mixed results. One guy loved it. My wife didn't make it through one round with it. We had to find her a different gun to finish the round. So, first thing: make sure the gun fits you. If it doesn't you won't like shooting it.
That said, I generally believe that the Baikal shotguns are fairly solid values. The stocks are crude, poorly finished and don't fit most Americans. But the guns go bang, time and time again. One of the guys I shoot skeet with uses a Baikal over/under and likes it well. We shoot once or twice a week, generally three or four rounds (of 25) each trip to the range. I've never seen this guy have a problem with his gun. Another fella used a Baikal for about half a season before he bought a Citori. He never had a problem with his either. By comparison, I've seen a couple of guys who brought low-end Turkish guns out experience problems. The Mossbergs/Savages, etc. have a reputation for broken firing pins, triggers that double and other reliability problems. You almost never hear that about the Baikals.
FWIW, I also own an older Baikal, a IZH-54 that was made back in the '60s. It's an entirely different gun than the current Baikal offerings. Folks that know Russian guns will tell you that the IZH-54 is the best shotgun to ever leave the Baikal factory. I really like this old gun. It fits me and I shoot it pretty well. Everybody who handles it is pleasantly surprised by its quality . . . You won't find one of these on your local dealer's rack but, hey, I'm going to post a couple of photos anyway . . .
It's been rode hard and a lot of the case hardening is gone but it still shows decent workmanship (again, you won't see this on the current Baikals). It's got a Greener type lock and is still tight, despite the left-of-center lever rest position:
note the servicable firing pins and captured screws, that's a good sign . . .
bone, not plastic, butt plate . . .
Unlike current Baikals, the stock on this gun is designed to fit a real human:
ETA: OP, I realize I answered your question from the perspective of a skeet shooter, without ever asking how you're going to use the gun. If you just want a Joe Biden special to guard the home front or to blast stationary targets, the Baikal should be great. Gun fit really only comes into play when you're trying to connect with flying targets.
