I have a number of VX3s and bought two Fullfield E1s in the last year, a 3-9x40 and a 4.5-14x 42. I'm neither a self-anointed Internet scope expert or a real scope expert. I don't know what eye relief measures on either scope, but no complaints with either Burris or Leupold in this regard. Both depict clear, vivid images. Adjustments work well on both.
After many years of buying, selling and trading many scopes and reading negative reports on Leupolds, I do know that Leupolds retain a high resale value and are easier to sell than just about anything else.
