Is heavy vinyl worth it?

I just got into vinyl and am starting to build a vinyl collection starting from zero records. I bought an OJC copy of Sonny Rollins' Way Out West and it sounds great even on just regular vinyl. I'm wondering if buying the heavy vinyl (180g, 200g) is worth it in general...they're upwards of $30 in some cases. Do they really sound better? What are the advantages? Is it a longevity issue? Do the heavy vinyl versions sometimes contain better remastering?

Thanks,
Winston
