What is the best Bitcoin Wallet?

I'm curious how people are storing their bitcoins.

Is anybody using coin base or blockchain wallets? Or is there a better 3rd party option? Which is most trustable and do any 3rd parties offer any insurance?

If using your own wallet, which version are you using? Any experiences with the light- version that doesn't require a complete download of the blockchain.

Is anybody cold storing their coins? How?

Thanks for your replies.
