Con No pretty ligatures
Ligatures are nice-to-have in languages such as Swift.

Bold characters are not the same width as regular characters so the typeface is not consistently monospace.

Lines in items like midnight commander, the treeview in htop, tmux panes, the tree command, et al., have ugly dashed lines instead of straight lines with sharp corners.
