I use Tamsyn (6x12 on lower res screens, 7x14 on 4k monitors), http://www.fial.com/~scott/tamsyn-font/ but it's getting more and more difficult to use bitmap fonts these days. Firefox recently dropped support for them, gtk support is hit and miss.
I like fonts that are easily readable when small so I can get more screen realestate, and bitmaps are the best for that, but 3270 is pretty good as well.
Where I can't use Tamsyn I use https://github.com/rbanffy/3270font
