I've been using the ASICS for years, through various seasons.  Tried the 2000 series on one foot and 1000 series on the other foot - barely felt any difference - the 2000 was a BIT cooshier, so maybe important for heavier runners or runners with big running volume.  If you run under 30 miles a week and are in the healthy BMI, save your money I say.  Also consider buying a 1/2 size larger than street shoes.

Only negatives would be that these shoes are not good for me when running without socks.  I get a hot spot after 20 minutes under my arch.  Also if you have long toenails and no socks, you might see a hole appear one day on the top mesh.  Lastly, the top mesh breathes great but holds mud nicely, too.
