I have my grandparent's grandfather clock, and my sister will get my mom's. I like mine. It's a piece of family history, for one thing.
If you are worried about it chiming, don't worry. 80-percent of the time, I don't even notice it. It chimes four times an hour, and I really go hours without hearing it (or noticing it, at least). My brain just tunes it out. It doesn't take long for your brain to adapt, either. It is right outside my bedroom in a hallway, and rarely hear/notice it in bed.
But, on many GF clocks, you can turn the chimes off. On some, you can even turn them off just at night.
