Technically evince is xpdf-based; poppler is just the name of the xpdf code that was turned into a shared library. The same conclusions for crashiness can be reached via the same speculative logic that I made for performance. > On the other hand, xpdf opens all > files without any problems, but can be a bit slower in scrolling > sometimes.

If you can pinpoint some example files that crash evince but work fine in xpdf, I will test them. So far, I have not encountered any issues myself. Gentoo has been shipping xpdf-poppler for a few years now, and I haven't seen any complaints of your nature there (although I have not done an exhaustive search).
