I don't think I've ever had a bad-sounding RCA Dynaflex, which weighs in at a whopping 80 grams!
I have a lot of fine-sounding 180g audiophile pressings from various sources. The 200g pressings, OTOH, are probably more trouble than they're worth. The extra thick lump of vinyl makes it very difficult to press uniformly and keep all that vinyl at the same temperature and softness. I have two Classics Records 200g pressings. One is very crackling and noisy in places, the other is great.
I also have a 150g red vinyl Classic Records pressing and it's fantastic.
It has more to do with vinyl quality, mastering, and QA during the pressing process. Using a record grip or clamp helps make the playback quality more uniform. If a 200g pressing sounds better to you than a 120g pressing, it probably has more to do with how the difference in thickness affects Stylus Rake Angle (SRA, aka VTA or vertical tracking angle) than the thickness of the pressing itself.
