There. I said it. Before I start getting mindlessly bashed, let me explain my reasoning. In terms of weapon balance: MW3 has a balanced weapon set, except for a few overpowered weapons, and a few underpowered weapons, while for BO, the Stoner dominates the LMGs, the AK74 dominates the SMGs and Stoner, and the FAMAS and AUG dominates everything else. For weapon uniqueness, most of MW3's weapons are unique for the most part, while half of BO's weapon stats are just copied with each other, and the SMGs all just feel the same. Another thing is that MW3 runs much more smoothly than BO, and is more fast paced. This makes it much more fluid and fun in my opinion. The worst part of MW3 is easily the spawning. However, I would much rather play a game with bad spawning than a game with bad hit detection. Bad hit detection leads to constant BS kills and constant rage, especially when one's the last man standing in SND. Bad spawning just isn't as noticeable and annoying as bad hit detection I believe. A point I'd like to make is of the strike packages and weapon patches. IW did try to bring innovation with its strike packages. Although the support needed work for sure, specialist was nice and having 3 different styles of killstreaks I thought was a quite nice and fresh innovation for it. The weapons were pretty badly balanced at first, but we oftentimes forget how many patches went out to try to fix this issue. Of course, we could definitely use a few more, especially with the shotguns, but the weapon patches were given far more attention by IW than by Treyarch. MW3 had several weapon patches, BO had almost non. Simple as that. Another bad thing about MW3 is that every map is for the most part small and close quarters, which helps lead to the bad spawning. Although this is definitely a bad thing, AT LEAST it leads to near-constant action, which can be quite fun if you're not getting spawn killed. One other thing that's said is that BO has more customization than MW3, what with the emblems and face paint and such. Although this is true, one has to remember that face camos aren't that very noticeable. Certainly not in 1st person, and not really much in 3rd person either. However, sometimes people forget that MW3 has weapon leveling and proficiencies. Weapon leveling gave a sense of...well...leveling up with your weapon. It was a nice addition that made you feel pretty cool to fully level up your weapons, rather than just buying what you needed and being done with it. Proficiencies undeniably added a sense of customization to your weapons, and an extra layer to weapon depth that I feel is underappreciated. Lastly, one of the major complaints of MW3 is the deathstreaks and underpowered explosives. This is also bad, no denying it, but I think I would rather have underpowered perks and overpowered deathstreaks, as opposed to overpowered explosives and overpowered perks like in MW2. Deathstreaks don't happen all that often either, considering how many times you need to die for them to happen. To add on to that, underpowered explosives in a way leads to more gun on gun gameplay, which I believe we could all appreciate. Well, there you have it. Rather than just saying that one is better without any supports or arguments, I've given plenty of reasons why my personal preference goes to MW3 than BO. Have fun bashing on me, dear MW3 haters/BO fanboys!
