Respectfully, I'd reccomend that you go with neither. It's natural to be interested in these big name wallets, but they aren't worth your precious time.

This post goes over really well why you should seriously avoid use coinbase's wallet, except maybe temporarily to buy coins and then transfer them to your own secure wallet.

Metamask is very insercure and uses only ETH and other risky, centralized coins.

Try to use open-source Bitcoin only wallets, like SBW, Blue Wallet, Electrum, Sparrow, etc. They are far more secure, they don't hide things from you, and they have focus on the most secure and decentralized monetary protocol there is.

It's really tempting to see the other wallets as more versitile because of how many different coins they can hold. All of us went through that viewpoint at some point. The thing is, Bitcoin is the only one that truly does something paradigm changing. Even more than that, the safety and focus Bitcoin provides opens you up to a far more secure, profitable, and free future than altcoins will.

Hope this helps you out friend. Cheers :)
