Using an Op-Amp as a Comparator: Pros and Cons

Hello everyone!

I have an OP484 opamp and was thinking about using it with positive feedback and use it as a comparator. To limit stress I could just use resistors to limit current. But My question is if using a an Op-Amp as a comparator is a good idea. I know I read somewhere before of an application note talking about pros and cons of using an op-amp as a comparator.

 

Can anyone help clarify? or any possible problems/issues/limitations that I should be aware of? and if they know that application note I am talking about, can you help me find it.
