'Is Black ops better that Borderlands' Sorry for being picky but it should be 'better *than* Borderlands' and to answer your question, Nope, nowhere near the benchmark Borderlands has set.
There is a huge difference between the games, making it hard to compare them. But if I had to pick one I would say Borderlands, and that its a lot better.
Definitely Borderlands, it has a ton of replay value and good co-op multi-player. Black Ops might seem like an amazing game at the first look, but beware- it's multi-player is the only really good feature in it, and that is plagued by terrible connections and constant host migrations (Once the game I was in froze three times to get different hosts, and I have had well over twenty or thirty servers simply disconnect in the middle of gameplay.)
In the long run, Borderlands and it's low-priced DLC's will keep you entertained well past BO's expiration date.
