Prior we didn't give a fluke about record weight, but lots of good quality pressings especially classical had been on heavy vinyl reaching 200g. What I noticed that noise floor on heavy vinyl is lower which is the crucial factor for classical music. For R&R it's all subjective and more would depend on mastering quality.
For me etched letters RL next to printed STERLING on the dead wax is more preferable than 180g.
