I recently purchased 2 Einstiens and 2 AB800's. I was pretty sold on Elinchrom until the Einstiens came out. I believe they are both very good but for the money I had to spend I decided on the Einstiens. Honestly I do not think you can go wrong with either.
It is known that at very lower power settings it is possible that AB's can shift in color. If Paul Buff did not have the Einstiens I would have bought be Elinchroms because I feel like there were a better product than teh AB's and worth the extra $$. I feel however that the Einstiens has imporved the issues and I am very happy with those. I try and use the AB's for background light and try and keep the power levels up.
Just my .02.
