when they come stock ego 8 simply due to having the screen curebolt and decent rammer and stuff in.
if the etek has or you are wanting to upgrade the etek with the likes of star frame, zic kit and cure bolt then i would say they are exactly the same
cost when new and stock etek cheaper but once upgraded with the above then you are looking at the same price or near enough
plus imo i would say the ego8 looks much sexier
hope this helps bud
