For me, the biggest problem with the 2600 is that there just weren't that many fun games on the console, even at the time. I never wanted one despite immediately being drawn into video games forever with arcade games like Pac-Man. I could enjoy playing Combat and Space Invaders for an hour or so at my friend's house, but we found ourselves right back in the arcades popping in quarters and being fully engaged by comparison.
There will always be more mediocre games than good-to-great games in a system's full library, but the 2600 was by far worse in that regard than any other game console that ever matched its success. It certainly made its mark on the industry, but it also crashed the US home market with a multitude of terrible games that had no identity, originality or engaging gameplay whatsoever. And even its best standouts like Pitfall have aged pretty poorly compared to classics on the NES a generation later. I still respect the 2600, but it's definitely not the "best" console per this thread's criteria in my humble opinion.
