GTK & Pango use fonts from fontconfig, not from X11, so it's not expected
to match xfontsel (which uses X11 fonts). Among other things, Pango 1.44
dropped support for Type 1 & bitmap fonts, which X11/xfontsel still support,
leaving TrueType & OpenType font support. One easy to spot difference,
fontconfig uses more natural names, like "DejaVu Sans Mono", while X11 uses
the older naming format with the 14 dashes separating fields. Visually,
if the font is anti-aliased or LCD optimized, it must be fontconfig, as
the X11 font system doesn't support either technology.
https://www.x.org/releases/current/doc/xorg-docs/fonts/fonts.html
describes the difference (using "Xft" for the fontconfig system),
but it's about a decade behind the latest changes now.

As far as I can tell, the "system" font for mate terminal and such is:
"DejaVu Sans Mono", or

Based on what I see with xfontsel, it looks like emacs may be using:
-misc-dejavu sans light-extralight-r-normal--0-0-0-0-p-0-ascii-0
I tried playing with the options/Set Default Font in emacs.
I'm not sure why, but emacs shows a lot less than xlsfonts does.
Here's what I have (from "save options") in both builds.
(custom-set-faces

'(default ((t (:family "DejaVu Sans Mono" :foundry "PfEd" :slant
normal :weight normal :width normal :height 113)))))
There seems to be a change in either the fonts or the rendering, from
the older OI build to recent ones.
The examples shown by "xfontsel" look too light in some cases too.
I'd appreciate tips on how to track down this problem.
Thanks

If you are using the gtk variant of emacs
That's the one I'm using.
then it relies on pango for
font rendering and layout which in case has dropped support for older
font types a couple of months ago.
So your problem might be that you are trying to use an unsupported (by
pango) font type and thus rendering results look ugly.
You might solve this be choosing a font of a supported font type, eg. a
truetype font.
There's no indication of truetype in the list of fonts that emacs
displays. In fact, emacs will often tell me that a font does not
exist when I select that font from its list.
