Glyph variations are fine as long as there is
a) never a contrasting usage in the same context
b) a common practice of alternating presentations w/o change of meaning
c) a common understanding that the details of presentation are stylistic

In this case, one or more of these conditions appear not to be met.

>> The most common symbol for the quarter tone flat, from what I've gathered, is a reversed flat sign. Some composers use the flat with stroke. One potential complication: AIUI the Arel-Ezgi-Uzdilek system for notating Turkish music, which divides each whole tone into nine koma, uses both, along with a few altered sharps.
