I don't think that JKR has really put much thought into it, so on one level the relative popularity of vampires doesn't need to make sense.
But to actually put a reason behind it...I suppose in the wizarding world vampires may be idolised in the same way are in this world. Plus, as you said, vampires (presumably) have more control over themselves than vampires.
The Ministry might not have such a problem with them because of their form. Vampires can pass for humans; there's no way a werewolf at that "time of the month" could.
Alternatively, there's the idea of a vampiric thrall, which I don't think is canon but I believe could be possible within Potterverse. Even if there are vampire-specific laws, they'd be tricky to enforce if a vampire could CONTROL YOUR MIND. D:
