I don't claim to be an expert, but I'll give you my opinion. I think PreRender happens too late in the event process for a lot of things. I tend to make all of my calls in either Page_Load or (if I need it to happen a bit earlier) in Page_Init. I would think Page_Load is generally the "best" generic place to put code since viewstate has loaded by then, but it's still early enough in the process for the most common things you need/want to do during the page set-up. You can't intercept thing too many things by the time you hit PreRender (ex. postback events), it's too late to load controls dynamically, etc.
