Watch out for coinbase--if the site shuts down, they keep your wallet file and your coins are stuck there unless they give you the wallet or reopen the site.
That's why I like blockchain.
What if I just use them to print paper wallets though? I mean, the odds they shut down in the same 10 minutes it takes me to figure out their paper wallet probably isn't a risk. They have a lot of backers, and being a company in the US I feel a bit more secure with them in a way.
Regardless, I'm trying to spread out a bit, multiple wallets for different purposes. Other side of the coin is the US govt could decide to block internet access to Blockchain.info. Sure, I know I know, probably not going to ever happen, but with them being in the UK I don't want to rely on them exclusively, especially when I have an easy paper-wallet option on Coinbase.
