Which one is better dps?

In general you can get approximate weapon speed comparisons by doing (10 + speed - booster). So for a speed 6 weapon on an aran, it's (10 + 6 - 3) = 13, vs. (10 + 7 - 3) = 14.

So Arcglaive naturally does 14/13 times as much damage. Which makes the two weapons basically indistinguishable for dps.

Ahh, that clears it up a bit, the main reason i wanted to see which one was better was because i intend to sell one of the two, although the dps is indistinguishable, any opinion out of the two which one you would keep if you were in my situation(arcglaive having less range but faster, eclipse having higher range but 1 speed slower)?
