[XeTeX] arabxetex vs. xepersian

[Axel Kielhorn]

Reading the documentation of the XeTeX packages I want to mention in lshort, I came across two packages for Farsi:

arabxtex supports:
arab (Arabic)
farsi (persian)
urdu
sindhi
pashto
ottoman (turk)
kurdish
kashmiri
malay (jawi)
uighur

xepersian supports only Farsi, but adds command names in Farsi as well.

The later seems to be aimed at native speakers.
Is there any reason to prefer one over the other?

At the same time I noticed that there is no package for Hebrew.
Is bidi (and a correct font) sufficient to write Hebrew?

Are there any fonts recommended for either language?
