Have you tried the Delta2? I own both and I find the Delta is definitely better than the Atlantis, firing both at 30W and even not taking into account the rebuildable deck option the Delta has.. The only thing I wish they had is a different stainless steel casing that lets you see the juice a bit better rather than just those slits.

I don't know if this is much of an issue, but the Atlantis is known to not take impact very well. I have a couple friends who dropped theirs and they either stopped working or become very shoddy at whether or not it'll fire.. The Delta seems to be built way more solid, though I've never had first hand experience of dropping them. (The delta has a steel casing around the glass, so I'd assume that's just a bit more added protection as well.) Again, I do own both, and neither of them has given me any trouble. But simply based on performance, options, and sturdiness... Delta takes the cake.

The subohm seems to be the closer contender, even though I've only played around with it a couple times so I can't make a fair comparison on this one.
