Sliding closet doors vs. bifold doors

[Wesley W.]

In your long-term rentals, which do you prefer and why?  What are the pro and cons of each?  Which is more durable? 

I'm building a closet, and trying to decide which kind of doors to use.  I don't think the room entry door's position/inswing will impede either kind of closet door.

Thanks in advance for your input.
