Well Red Wine adds 2 years to your life when you have a glass everyday, and White Wine adds 4. Its a taste preference. But due to benefits White I guess. Both are good though.
As an alcohol drinker for more than 25 years I can say that the red wine with the best price-performance comes from Portugal, a Douro DOC Tinto from 2005 is just great.
Best Red Wine I've ever tasted was an Italian SASSICAIA about 200$ the bottle.
