I’ve been using Fantasque sans mono for a bunch of years now.

Fira Sans / FiraGO by Mozilla, and the new SUSE font by SUSE.

For desktop, I’ve liked Lato, Source Sans Pro, and Inter to name three.

For terminal, I used Iosevka’s customizer to create a gorgeous Fira Mono-like variant that I call Iosevka Firesque:

[buildPlans.IosevkaFiresque]
family = "Iosevka Firesque"
spacing = "term"
serifs = "sans"
noCvSs = true
exportGlyphNames = false

  [buildPlans.IosevkaFiresque.variants]
  inherits = "ss05"

    [buildPlans.IosevkaFiresque.variants.design]
    capital-g = "toothless-corner-serifless-hooked"
    capital-q = "crossing-baseline"
    g = "single-storey-serifed"
    long-s = "bent-hook-tailed"
    cyrl-a = "single-storey-earless-corner-serifed"
    cyrl-ve = "standard-interrupted-serifless"
    cyrl-capital-ze = "unilateral-serifed"
    cyrl-ze = "unilateral-serifed"
    cyrl-capital-en = "top-left-bottom-right-serifed"
    cyrl-en = "top-left-bottom-right-serifed"
    cyrl-capital-er = "open-serifless"
    cyrl-er = "earless-corner-serifless"
    cyrl-capital-u = "cursive-flat-hook-serifless"
    cyrl-u = "curly-motion-serifed"
    cyrl-capital-e = "unilateral-bottom-serifed"
    cyrl-e = "unilateral-bottom-serifed"
    brace = "straight"
    ampersand = "upper-open"
    at = "threefold"
    cent = "open"

Fira Code and Caskaydia Cove Nerd Font for monospace. For other uses, I’m usually good with whatever the system ships with.

I find comic sans mono actually looks surprisingly nice for coding and terminal.

Lato, League Spartan, League Gothic are my three most used fonts by a wide margin. Lato and its variety of weights for most things, League when I am doing design work and need a cleaner title or header.

Lately ive been weirdly taken with TT2020 Style G, which is an odd name for a no-name font that replicates an old imperfect typewriter. For whatever reason, switching my writing software to that (Manuscript) suddenly fired up my writing flow.

Fantasque

Iosevka

Hack nerd font is my go to for terminal use.

I don’t have a reason to move away from the Fedora defaults except for monospaced fonts.

Terminal wise, terminus is my default. It’s so clean, and it looks good without anti-aliasing.

Roboto Mono is my current preference for monospaced fonts.

Adobe Source Code Pro and JetBrains Mono are good alternatives as well.

Ubuntu Mono for terminal, code, and data, Open Sans for the rest

For sans-serif, I use Mona Sans. For monospace, I use Monaspace. I think it’s a good-looking combination.

I use M+ Fonts for most of my stuff.

Since basically forever I use DejaVu Sans for UI elements and DejaVu Mono for the terminal.
