i honestly would get the JG version and save yourself 30$.
even retailers claim there is no difference (see airsplat) and you would think they would overhype the minutest differences.
Well I'm sorry to say you are mistaken. There is a greater difference then you think. Internally, Echos have better spring guides, piston and gears. And echos also have a 30 day manufacturers warranty. So the 30 dollars is worth it.
Also a lesson has been learned, "Never believe the crap that airsplat says." lol
