A few you can try:

• Debian
  
• Arch
  
• Ubuntu
  
• Fedora
  
• CentOS
  
• Tails
  

All of these have different variants/rebrands out there, as well.

haha dont you remember, she hates debian :'D
but for all except that one, I think these ones are good.
ubuntu is generally better than debian imo, and also, Arch is better than ubuntu and fedora.
fedora is also pretty good btw, you should give em a try.

Ironically, Ubuntu is derived from Debian. As always, these things are subjective and there's no "right" answer. I've personally used all 6 of those over the years (both production/consumer), and Debian is my go-to.
