So EQSL far outweighed LOTW for confirmed QSO's.
I have about 71% response rate for eQSL, vs. 50% for LOTW. I think the primary reason for the difference is non-use of LOTW by non-US hams. A second reason is the difficulty of setting LOTW up, versus eQSL.
Actually the difference is in how the contacts are made. As I posted above, I have several WAS awards but I don't even qualify for the eQSL equivalent. The same is true with DXCC. I have 131 confirmed DX contacts with LoTW but only 108 with eQSL, so this dispels the myth that DX operators don't use LoTW.
So why do I have more LotW confirmations (and awards) than with eQSL? Contesting! With 100 watts and a vertical, I am not a "serious" contester, at least not in terms of actually winning a contest. But OTOH, most of my confirmations come from contacts made during a contest, both domestic and DX. Especially now that LoTW will accept Cabrillo log submissions is another reason contesters prefer it over eQSL (IMHO).
So I think in general. contesters tend to be more concerned with confirming their contacts than "casual" operators do. I know a lot of people dislike contests because they think there are too many of them (which is another myth, but we won't go there), but you (not you specifically, but "you" meaning those people who say they dislike contests) might dip their toes in the water during a contest if for no other reason than to bolster your confirmation rate.
