yeah, blockchain.info is more secure. 
Have you tried it? Did you experienced any problem or the likes? Is it a hassle free transaction?
I have tried it, so far no problem.
Make a backup before start using it. Send the backup to your email and one .pdf backup(paper wallet). It would be good. It is best to store it somewhere safe and then delete the email.Still prefer desktop wallet over online wallet. Remember input.io?
Blockchain is different but still offline is better.
