Damn straight. Personally I think Stern may have been the best of them, but that entire group, writers and artists both, accomplished something we haven't seen before or since. Back when DC was doing those weekly books like 52 and Countdown, they talked about how it was such a big achievement and so hard to pull off, but the Super books had basically already done it, and maintained their momentum and quality for a huge stretch of time. There's a reason people say the triangle era is a hidden gem; it rarely gets the love and respect it deserves.
Just to put it into perspective; that run brought in two elements that have become core ideas of Superman's mythos; his marriage and his death-rebirth, and those ideas have been used for nearly three decades across multiple media formats/continuities and are nearly as entrenched as Smallville, kryptonite, and Jimmy Olsen. The vast majority of main canon runs can't imagine even leaving one idea behind that becomes half so popular, and the triangle era did it twice.
Y'all know I'm not a big fan of the early post-Crisis' take on Clark, and *I'm* saying the triangle era was f*cking genius; that tells you how good it was.
