Um, so, it was pointed out to me that I missed some major ones. Even
some I wrote personally :)
Drag Reorder of columns
http://www.smartclient.com/smartgwt/showcase/#grid_appearance_columnorder
The CubeGrid (multi-dimensional data model support)
http://www.smartclient.com/index.jsp#basicCube
http://www.smartclient.com/index.jsp#analytics
A whole range of autoFit behaviors (not just this sample, the whole
folder)
http://www.smartclient.com/smartgwt/showcase/#grid_autofit_filter
Also, the fact that all of these features also apply to TreeGrids (eg
frozen columns and full-row editing).
Also, SmartGWT's data connector architecture and it's ability to
support multiple caches on the same large data set, with independent
search criteria, sort direction, etc. This is needed for dozens of
use cases involving large data sets, such as moving records from one
category to another by drag and drop. GXT's "Store" is extremely
primitive by comparison and a lot of manual effort is required to
achieve something like this:

I have probably missed another 9 major grid features, and this only
covers feature advantages related to grids, however this and my
previous post are probably the best answer to the original question:
what are the technical advantages.
