Not necessarily. Generally, the best recording I have are originals pressed on normal vinyl, not the heavy weight reissues. While some quality reissue companies do use heavy vinyl, often heavy vinyl is just a gimmick to attract audiophile purchasers. I find that the majority of the heavy records I get are warped, probably because the pressing cycle duration was not increased as it should be for thicker records. I particularly hate 180-220 gm records since they require VTA adjustment to be played optimally. Easy if you have a Wheaton or a VPI arm, not too bad if you have a Graham, a real pain with the Vector (which I have) and impossible for some.
Best records, in terms of pressing quality, that I have are Japanese or German in origin, and they are all quite thin, but meticulously pressed.
