Blockchain.info mobile wallet is not independent wallet, it requires pairing from web version via QR code so I am not big fan of it. Whereas, Mycelium is single-handedly most efficient mobile wallet presently. It provides everything a person needs from Bitcoin wallet: multiple accounts, dynamic addresses, Seed, pvt keys, buying/selling within app, signing a message, cold storage, etc. The only drawback it has is its complexity. Mycelium is providing such huge bunch of features in few MBs of mobile wallet so it is little difficult to use certain features like making backup.

Electrum mobile wallet is also a good choice. A simple client wallet providing basic features and providing various versions of Bitcoin addresses like Single, Dynamic, Segwit, etc.
