I drink both. No preference. On weekends I grind beans and drink Ruta Maya coffee.
I think I've had both in the form of "office coffee" or waiting on my oil change at Jiffy Lube. I'm rather partial to another value brand that Publix grocery here in Tampa offers at Buy One Get One Free occasionally....
I'd say Maxwell House. The best part of waking up is Folgers in someone else's cup.
