How does everyone feel about buying ETH through paypal?

I didnt know Paypal offered ETH til the other day. I threw $100 in it and plan to continue to do a $100 or 200 here and there every now and then. Ive always been pretty sketchy on crypto and just buy index funds and stuff. I feel like getting ripped off by paypal is highly unlikely but i understand the "not your wallet, not your keys" thing. For a very small time ETH investor do you think this is ok, or should i use binance, kraken, etc?

Also. What is the best exchange in your opinion? Ive followed crypto for a long time but always thought it was too volatile for my liking. Open to suggestions. Thanks!
