It's not nearly a value as the McDouble as it carries a price tag of $1.99.
The first thing I noticed biting into the Daily Double was the lack of ketchup or any sour bite. It makes for a blander burger eating experience (I recommend just getting a packet of ketchup and squeezing a little on). There was a fair bit of mayo, but it wasn't too flavorful.
The cheese was very nicely melted between the beef patties.
The bun wasn't toasted very well. It's like they only managed to toast the very edges.
Overall, the Daily Double doesn't really stand out... at all. It misses any hint of an acidic zing to bring out the flavors of the burger. I like that I get some veggies, but I would opt for the regular McDouble and save myself the extra dollar.
