This is one of those Dr. Faulkner things ... you can't win, so don't play.
I much prefer to use my own pantheons. I recently rediscovered this the hard way.
Recently, I rebooted my entire campaign world when I moved and started with new players. I decided to make my setting more accessible, so I dropped out my homebrew Gods and replaced them with Gods from the Dawn War and Greyhawk pantheons. However, these were primarily just ways to use familiar names on reskinned versions of my Gods. As a result, some of the Gods don't perfectly match the ideas of some of the players as to how a God should be. For example, my Melora is a Goddess of Natural Forces, but not of Nature (as in plants or animals). So, she is responsible for Hurricanes, Earthquakes, Forest Fires, Tsunamis, Heat Waves, Storms, etc... but not of cats and ferns. When I had a homebrew name associated to this deity, it was no problem, but because so many players knew Melora (from Critical Role, etc...) they've struggled to understand what she stands for in my setting. To that end, I feel like I made a big mistake in using well known God names in my setting and wish I'd stayed with the homebrew pantheon names I built over 4 decades.
My advice to new DMs is to start using an established setting and experiment a bit, but to then spend a little time building your own setting and making your own Gods. Having a setting free of baggage is liberating.
