Hi Peter,
Thanks for using Syncfusion products.
The Sf prefix is a naming convention that we have adopted
for 2nd generation/newer controls since 2012. Their main advantages are much
better performance, touch friendly and share API across WPF, Silverlight, WinRT
and Windows Phone. The recommended general guideline for new projects are to use the Sf series of
controls.
Please let us know if you have any queries.
Regards,
M. Sheik
