I love coinomi wallet. It was one of the first wallets I ever used it. It's getting improved every month.
I am sad to know it's closed source, which is the only downside of this Wallet for me.
I also use Coinomi for a long time without any complaints. But I think it's worth to say that there was one security issue on Coinomi some time ago:

That is not a reason to call them the best wallets to use. I prefer a wallet where only me can have full control. I personally won't add Coinbase, Blockchain, or something similar to this list.
First of all it's not Blockchain, it's Blockchain.com, I think we need to use accurate names to avoid confusion. I'm not saying that it's worth to use Blockchain.com wallet, but actually you have control of your coins on this wallet because there you recovery phrase.
