From Allan Espinosa:

xfig is a great clipart diagramming editor the “wysiwyg” component does
not look too good when zoomed out. for example, a polygon created does
not look like a “polygon” but just jagged lines. But when zoomed in the
polygon can be seen. The rendering to postscript was also exceptionally
good with anti-aliasing. what are you guys using to edit *.fig files?
will compilation with xaw3d widgets fix this or the xaw3d libraries are
just eyecandy? the screenshots from the xfig.org site looks nicely
rendered but i thinked they zoomed it enough not to show all the ugly
aliasing and poor rendering

xfig is good for quick and dirty diagrams but if i want to have good
looking pictures with subscripts and formulas I use GNU pic/ dpic with
m4 macros. the circuit_macros package from ctan.org is one of the best
schematic drawing packages out there. The output looks like text-book
quality schematics!
