I don't bother with chapter numbers/chapters. I just put a few astricks to symbolize a scene change or a break when it feels logical - whether it's 1 page in or 10.
There's nothing wrong with scene breaks, I use plenty of them, but personally, I would HATE to read a book that didn't have chapter breaks. Trying to read it would be exhausting, like there's nowhere to catch my breath, nowhere to stick a bookmark and take a pause. Really excellent books will have chapters that end on such an exciting note that you don't want to stop reading there, you turn the page and keep going. But to not have chapters at all? I couldn't deal with that.
As for the original topic, I gave two of my novels chapter titles while I was writing them, just to help me keep track of the convoluted plot, but I will delete them before submitting the manuscripts to agents. The first one had old-fashioned long titles that summed up the chapter, like, "Chapter One: In Which Cera Meets Jorn and Wonders if the War-Plague Will Ever End." The second novel had short titles, generally one or two words that summed up the essence of that chapter, like, "Chapter One: Buried Alive".
Like others have said, I don't want the content of the chapter to be spoiled by the title. That's why I plan to delete the chapter titles before subbing the manuscripts. I'll just number my chapters and leave it at that--with one exception. If I'm switching POV from chapter to chapter, then I might title each chapter with the name of the character whose POV it is, just so readers don't get confused.
Now, if there's a quote at the beginning of every chapter, that always annoys me and I don't bother reading it. A quote at the beginning of the novel, or at the beginning of each "book" or "part" within the novel--those I'll read (if they're brief), because if the quote is well-chosen, it can enhance the story. But sometimes the significance isn't obvious until after you've finished reading, and who wants to flip back and re-read the quote, just so you can say, "Ah! That works"?
