For the PDF in question, that displays numerous

The Helvetica entries show Type 1, no embedding. The two [none] entries
show Type 3, embedded. fonts-liberation and fonts-liberation2 are
already installed.
Helvetica isn't a Microsoft font. It's a sans-serif commonly seen on Macs.
The usual Microsoft replacement is Arial, but I don't think it's 100%
metrically identical, so Liberation Sans wouldn't be either.
Of course, it's possible that the Helvetica fonts aren't actually used anywhere
in the document and that the two nameless fonts are derivatives of something
else altogether. That would be far from the stupidest thing I've ever seen
anyone do with a PDF file.
What is occurring, was that the layout of the PDF
viewed with any of the
aforementioned packages (except Vivaldi), wasn't 100% perfect. For
example, spacing between the letters was uneven.
That suggests a kerning problem, and possibly an unsuitable font
substitution. You may want to dig into your distro's information on
fontconfig. The command "fc-match Helvetica" can be used to see
what your system's substitute for Helvetica is.
It's also possible the designer was a bonehead and adjusted the spacing
between letters without embedding the font. That's . . . a little more
difficult to fix.
