Is there be a reason to prefer one over the other notation?
"x²" versus "x<sup>2</sup>"
"𝑃" versus "<i>P</i>" for a mathematical variable
("𝑃" is U+1D443 "MATHEMATICAL ITALIC CAPITAL P".)

The former results in an essentially better rendering, since a
superscript glyph, as created by a font designed, is used for ², as
opposite to using a glyph for 2 in some superscript style (which is poor
by browser defaults and difficult to tune), normally causing uneven line >spacing when used inside a paragraph.

Actually, in the fonts in which I have seen it so far, the
"MATHEMATICAL ITALIC SMALL ALPHA" 𝛼 from Unicode looks more like what
I imagine an alpha would look like than "GREEK SMALL LETTER ALPHA" α.
It is also possible that the "MATHEMATICAL ITALIC" symbols
already have some italic correction built-in.
Here's a clarification, but it requires a Newsreader that
renders all spaces verbatim (even a sequence of several
spaces at the beginning of a line) and a monospaced font.

I was able to tune Thunderbird to display your message that way, but I
am unable to recognize the difference.
I prefer them to intersect forming an angle of about 120
to 150 degrees (on the left side of their intersection),
not about 180 degrees.
An "alpha" is a line that describes a kind of semicircle on
the left side.
On the right sight, the two ends of that line meet in an
intersection.

U+0251 ɑ vs. U+0061 a (which is a different sound)
U+0361 ɡ vs. U+0067 g (which does not represent a sound in the other variant)
This sounds like a font issue. The shape of α varies greatly by font, and in some fonts, it looks much the same as the Latin letter a in an italic typeface. I don’t think you can do much about this except select the fonts in
your list accordingly. Generally, for mathematical expressions, you should in any case use a serif font with a rich repertoire of characters (so that you won’t need to mix fonts), and this restricts your choices a lot.
In fonts like Cambria, Times New Roman, FreeSerif, and Noto Serif, the difference between italic a and italic alpha looks quite sufficient to my eyes.
