Just because less people play it, doesn't mean it isn't better.
Now, I haven't played both, so I cannot say which is better (I only have Halo 4 since it was a birthday gift, $ issue, not a lack of CoD fandom, I've been playing since 4), but there are many cases where a great game doesn't sell as well as it could. --- "Gary was here.

Sadly, I dont care how great Halo 4 is. Until some of my friends actually play the ****ing thing, I wont bite.
18/20 (literally, inb4lrnhowtoreducefractions) of my xbox friends play blops2. exactly one of them plays Halo 4, and the one who plays Halo 4 also plays blops2. --- not changing my sig until Shenmue 3 is officially announced.
