Not really, although that could change very rapidly.
The DDR motherboards are just becoming available... actually, im surprised at how many are listed as 'in stock' by retailers, yet there seems to be a bit of a shortage of reviews of them...
Due to not all manufacturers boards being available yet, its a bit hard to pick any winners. The main problem with DDR at the mo, imho, is the price of the RAM, its way to high to justify the cost, although not all RAM manufacturers have ramped up production yet, so that should change, the manufacturing cost of DDR is only about 5% greater than SDR (if you beleive the press releases).
And if you are not an overclocker, finding 133fsb tbirds is a bit hard
