Out of all the ones you listed, I prefer certain speakers depending on what you're after and what you're ultimate purpose is.
If you're a guy who likes to walk around the room while you listen to music, then definitely do not get planar speakers like Martin Logan... piss poor horizontal and vertical dispersion characteristics will lead it to sound muted at any other spot other than the sweet spot. That said, I feel that the MLs will have the most cohesive if not the most accurate sound of the choices you gave me. Too bad the Clarity is the lowest in their ESL line (rather it's a Designer series speaker) and it sacrifices a LOT of what makes a Martin Logan ESL great....
If you're a guy who likes to rock it out, no other speaker in your list will be as good as the Deftechs.
If you're a guy who likes your sound to be a bit more on the warmer side of things... a bit more "romantic" as some might say, then the VA are right for you.
Personally, I own the Martin Logan Summits (their top of the line ESL aside from the Statements e2x) and I wouldn't have it any other way. Great horizontal and vertical dispersion considering it's a planar speaker... something the lower MLs like the Clarity does not have. Yet, I think even with the Clarity, they are the perfect speaker for someone who is critical and listens from a listening chair - eyes closed and all.

Good luck...
