You were a good 10 years ahead of me. I was using AOL and Netscape on a 386 Pentium back then. I started on Ubuntu, but I dislike Canonical who makes it. Therefore, I would try Linux Mint. It is a Debian distribution. It is good out of box. At this point I would give it to a grandma. If you want to be cool again, there is still Arch and stuff like that, but I have that and maintaining it gets old sometimes because custom built things break more during updates. Linux Mint or Fedora. I also hear good things about OpenSuse but never tried it.
