SMS Designated Coins...Still Learning

Ok, I know a lot of the Kennedy Half Afficiandos like the SMS variety (?). Through searching various sources I think that I've come to the conclusion that SMS stands for "Special Mint Set (?)." So, the special mint set Kennedy's (and other denominations) that were made for these sets are "preferable" to non-SMS coins of the same type. What is it that is different or preferable about the SMS coins?
If the above does not make sense...what is SMS and why is it desired?
Thank you for helping me continue my numismatic education!

SMS coins are "preferable to non-SMS coins of the same type? NO.
I for one collector would rather have a MS67 "Business Strike" coin to a MS67 "SMS" coin any day.
EDIT TO ADD: I have a 1966 MS68 SMS Kennedy that I would be more then willing to trade you for a 1966 MS68 Business Strike Kennedy.

Heck...I might even trade a 1966 MS68 SMS Kennedy for a "Downgrade" to a MS67 business strike

So would I, so I could sell it to you and buy more SMS coins.
