I used to be so obsessed with coinomi wallet because it support many altcoins, maybe because I find it more better than myether and copay and later I decide to try trust wallet, I was surprised that right after importing my private key all my altcoins are ready for me including every single ERC20 tokens I own, Trust wallet get rid of adding tokens manually and in fact it shows every price of the tokens that are listed and trading, now I can't stop loving the wallet, way better than coinomi now
I have been using that too. But as it's a mobile wallet i have some trust issues with the security. I still keep holding most in offline wallets.
