I just found I can only choose one, not both.

Provided that you use questions that a bot could not easily answer, I'd think either should work fine. I had problems with bots and added about 5 random questions (you don't have to answer them all at registration, of course, it only asks 1 of the 5 available at random). I haven't had a single bot since.

But, I hear that reCaptcha is really good too. As far as I'm aware, bots can't read/answer it yet. Though, I don't keep up on that stuff, so you might want to research that for yourself.

If you want to use them both, you might be able to use a plug-in to provide one of them, then use the built-in vBulletin verification for the other (provided that you're using a vB version that has them). Perhaps Cyb's plug would work if it doesn't just use the built in question/answer system? Or, there is another one that people use....NoSpam, perhaps?
