Personally, I would prefer the conventional Latin Modern math font instead of Palatino math.

Latin Modern is used by:

- Wikipedia. - Math.StackExchange. - Nearly all papers, including the ones hosted on arxiv in PDF format. - Nearly any math videos, slides/presentations, notes. - Almost everything, really.

Palatino just looks weird.

Also, I imagine that authors might do math formatting hacks that were only tested on Latin Modern, and might end up breaking on Palatino.

TL;DR:

Palatino :(

Latin Modern :)
