Looks like Masters swimmers have decided on the best new suit available right now - probably a combination of price / value / and length of use.
I am at the Long Beach SCM - west coast "nationals" and the winner is: The Blue Seventy by a ratio of about 50 to 1 over the LZR.
People are either wearing one of the older suits (some of them are to be had for $25) or a Blue Seventy. There is still a bit of "confusion" over which Blue70 to get - I saw quite a few of the open water models. But I think I have seen a total of 3 (including mine) LZRs at the entire meet. No kidding Speedo wants the coaches to ban the Blue70.
Personal comparison - 50 Free - Blue 70 = 23.25 /// LZR = 23.44 (but I had a poor dive and a poor turn - I would still rank them about even)
