Coinbase is a good wallet but you can't say best for everyone because Coinbase wallet is limited to some countries only. I don't think it offers services to the citizens of Indian country. In today's highly competitive world there are tons of wallets available which are offering good services at very low fees and charges. I like to use a wallet like Zebpay, Koinex, Buyucoin, and Wazirx. Apart from all these wallets, I like to use local bitcoins wallet where the security is quite high with escrow services and I use it during big government press release and events so that my coins don't get affected due to some negative news.
