I'd go for the Vortex simply for the fact that I personally don't trust Eotech when they say "oh yeah, we finally fixed those issues we couldn't fix for nearly ten years even though we told you before we did." They lied. Multiple times to multiple different people/entities. Sorry, but I don't have faith that they're capable of telling the truth.
Vortex, on the other hand, has never been caught in a lie (to my knowledge) and has awesome CS should anything go wrong. They're obviously working out any of the kinks from the system (hence why the UH-1 still isn't released) and I truly believe they won't release it until it suffers from none of the issues that Eotechs do/did.
My wife absolutely loved her Eotech because of how large the optic window was, but it had to be sent back for the refund after it started suffering from purge loss/reticle fade. She is patiently waiting for the UH-1 to be released so we can put one on her rifle.
