Coinbase is a popular exchange but seriously I can't really compare coinbase to binance, binance is one of the best exchange which you can buy and sell cryptocurrency easily without stress and low transaction fee your funds are very save there and you can easily withdraw your money to your local bank account without stress, there are lot's of unique futures there, you can easily set your buy order and sell order even when you are not online you can easily buy and sell your coin.
I am a user of Binance also but not coinbase. So I can't compare the two. I am already happy with what binance is offering. Never had any problem with them. Also, your funds are pretty secure as they have insurance in place. They have various financial offerings also so for me, binance is already my digital bank. Easy to transact with and the liquidity is really great. When it comes to storing your coins long term, better to store it in your wallet. Even using electrum wallet to store btc is also a better choice rather than storing your coins in a third party online wallets.
