I have actually been pretty lucky with my 360. I had one for a couple years until the disk drive went out on it so I replaced it with an Arcade version after that it's been working for years. Technically I had worse issues with the PS2. I had the earliest ones and right away, it began to almost literally eat dvd's and games. It would play them, but start grinding into the disks. I lost a dvd and game because of that. I sent it in and they replaced the game and movie for me. Then it had this loud whirring sound, so sent it back again and then the replacement after that worked great. They may have had issues, but Sony had great service then.
If I had to be honest, the NES was probably the crappiest for its obvious issues. I had one given to me as a kid and was probably a few years old by then, but I remember always having to deal with games not working right on it. Sure it was second hand, but I don't remember having to deal with as many issues as with that one.
