FWIW, I personally can’t stand ostentatiousness (is that even a word?).
Many years ago, I was lucky enough to win a Megillas Esther at a Chinese Auction. Along with the megillah, I won a silver case. However, the case was big, showy, with bells that jingled whenever you moved it and with ornate work on it. For me, it was just too much. It was beautiful, mind you — but just way too much for me. For years, I carried my megillah around in a zip-lock bag rather than use that thing. Eventually, my mother-in-law was kind enough to buy me a nice, simple, wooden megillah case as a birthday present, which I still use to this day. The ostentatious thing sits on top of my breakfront, empty and unused.
Perhaps that’s the same reason that I don’t have a fancy, silver menorah (I still use the same one my mother bought for me when I was about fourteen) and I don’t use a fancy silver matzo holder, esrog box, etc. Yes, some of you will say I don’t show any chashivus to mitzvos — and you’re entitled to your opinions — but I’m not changing the way I am at this point in my life.
If someone else wants to be ostentatious, I don’t begrudge them — I firmly believe that as long as it’s within halacha a person is entitled to spend their money as they see fit — bit it’s just not for me.
