SNES followed by GBA. I think a lot of people remember the N64 with rose-colored glasses. Outside of Nintendo IPs there wasn't much worth playing on that system. Most people can't recall a single third-party title on that platform. It was probably the only Nintendo console in which first-party titles were the main selling point almost exclusively. I had one when I was a kid and remember wishing I had my PS1 back (it had died less than a year of owning it).
People say the Wii U was a black sheep, but I had to disagree. It was welll known for its failures and there's not much on the system outside of first-party titles and a few indie games that made the console worth while. It was the only console I ever sold that I ddin't regret later on. I did eventually buy another, but only to hack and play Wii and Wii U games off of a flash drive. Let's not get started with the gamepad wireless module failing in many units. It's a ticking time bomb.
I also love the original Wii. It's the only modern Nintendo platform outside of the Switch that I really played a lot. It had so many games and finally had great third-party support. Of course, it had more shovel ware than you can shake a stick at, but there were some quality titles on that system.
