Its by far my favourite too (bcs of the just extract customisations I want - same with Infinity). Voyager might get close on visuals, but I prefer the ease/speed of use Eternity offers me.
However I never experienced crashes at all (not even with the early versions & Im using it since day 1/first apk built).
My only (and persistent) bug is related to various or possibly all sorting (posts, comments, inbox, etc), which works fine, but eg notifications in inbox don't take me to the exact post (or nowhere at all).
But I fund an ez fix - just backup your settings (in-app functionality), reset some or all settings in the app (via the app), and then restore settings (it restores everything, no additional fiddling). The whole manoeuvre takes less than a minute. Im my case resetting only sorting (not all settings) works most times.
