I will interpret "harsh" as the jumpy factor of a recenter you see with most common Web 2.0 maps (including your example of google as well as bing, yahoo, mapquest, etc).
Be honest, I (a developer, not a user) sort of like the smooth factor and implementation of the ArcGIS JS API "slight" recenter. But I gotta answer to the end users who actually use the tool everyday and have expectations.
Thanks for explaining your interpretation of the feature.
