ED maybe once in a blue moon will CTD but is one of the most stable games I have played. From a bug perspective I have never seen the issues with ships physics, planet issues that SC has. I'm not sure how they even get to comparing bugs and I really wonder if its actually ED players making the statements.
Multicrew is still a broken mess. Disconeections, players being in the wrong chair, the role panel glitching so players can't choose to be in the fighter or gunner etc. Ax combat zones also have a bug where only scouts appear instead of both scouts and interceptors. Oh and god awful green graphic glitch. It's an epileptic's worst nightmare.
And of course the dreaded rubber banding issue. Try shooting with your railguns when your target teleports suddenly.
These issues are just a few I encounter.
