The one of your childhood experiences (I bought an old ADI 14" CRT monitor, nothing special but it looks almost identical to the one I used until ~2008), or teenager envy (my small collection of Voodoo 2 cards I found for free in the early 2010s, and I took them because I SO wanted them and could not afford them in ~1998... now I can play those game in beautiful Glide mode instead of simply software rendering), or the one that spark your interest for some reason (say, Unix workstations of the 90s, because as soon as you boot one up it feels like $HOME, even if a machine is almost 30 years old). There is no inherently "great" retrocomputer: they're mostly all old crap. Sure, you can make money if you buy a SGI Octane low and resell it high, but it's pretty hard to get one for a low price... and I would get emotionally attached to it anyway.
