Sold Roth WANNA Buy BTC

So I am in my 50s and bought a chunk of BTC in 2020 that has been secured w a dusty old tresor for 6 yrs. I just sold one of our Roth accounts nnd am buying more BTC. I have a Gemini account and a Coinbase account. I know there are new places to buy BTC. Would you still go w/ Gemini or Coinbase ? What platforms are you guys using for largish BTC purchases now. I would rather pay a higher fee than use a place I don't trust. Who do you trust? After the purchase I would then be securing it w/ my trazor also. TIA.
