I had a 788 in .222 Rem. It didn't shoot particularly well with new brass, but after fireforming the cases it would put five shots into about 5/8" at 100 yards. With new cases, it would shoot about 1 1/4" at the same distance. I think the chamber was a bit on the large end of tolerances.
The main problems I had with the 788 were with the factory trigger, which can be replaced or tuned fairly easily, the hardwood stock which warped so much I had to replace it with a synthetic stock to avoid having to sand out the barrel channel every couple of weeks and the high cost of replacement magazines.
The last feature can be a major unexpected expense of owning one. That's why I would opt for a Stevens 200 over a 788.
They have an occasional problem with the handles breaking off the bolt (which I suspect is due to owner's using force to open a bolt stuck due to a high pressure round being fired). Replacement bolts are impossible to buy from the factory, but can be repaired, although fairly expensive, considering the cost of the gun, to do.
