Edmeades's zins from the 70s, Green & Red's from the early 80s, and Nalle's from the late 80s are a few of examples of zins I used to love.
Nalle's were pushing toward the superripe, jammy style that's the only kind I've encountered in recent years, but they were "only" around 14-14.5% alcohol.
Does anybody make balanced wine out of zinfandel grapes any more?
Primitivos I've always found flabby and hot.
Some of the cheaper plavac mali (Croatian zinfandel relative) wines I've tried have been interesting, but the more expensive ones tend toward the same excesses as in California.
