In terms of overall impact, I'd say they were all very close. In terms of the single player experience, I think Half-Life destroyed them.
I don't have a problem with reviewers saying those things as they're not necessarily untrue. It's easy to understand how the majority would see Doom II as being "smoother and prettier". Doom II did have a certain kind of flow that SS lacked in regards to movement. It was also released before the CD version of SS, and iirc the original release of SS was limited to 320x200 resolution.
So yeah, Doom II did have certain advantages even if the game itself was much smaller in scope and ambition. Those advantages may have been superficial to gamers like us, but I can see why critics would mention them.
