Its worth leaving it a couple of weeks after a new php release, that way you can test in your dev and mirror environments before placing it in the live environment.
We are currently testing 4.3.5 and apart from a single "make test" fail. It seems to be ok. Time will tell :)

Seems to be working for me. 4.3.5 is a bugfix release so it probably more likely that eZ publish becomes more stable from using it. But, as Tony suggests, test it before deploying.
It looks like 4.3.5 has some issues. If these affect you I would hold off till 4.3.6

In the spirit of release early, release often here is the first and hopefully the final release candidate of PHP 4.3.6. This release addresses 2 major bugs introduced in the 4.3.5 release. One of these bugs caused problems when loading dynamic extensions on Windows and thread-safe (ZTS) builds and the other involves incorrect handling of daylight savings time. A few other minor bugs were fixed as well. </quote>
