wallet on your phone will be quite risky because any person could borrow your cell phone and maybe he is a bad person and then hack to your mobile phone.
Why would you borrow your phone with a lot of money in it to someone? Do you borrow your wallet packed with money to "any person"?
I would recommend using blockchain highly trusted and full control
Bad advice as always. Blockchain.info, and generally any web wallet should be avoided when possible.
I am satisfied with blockchain performance and dont feel the need to switch to another wallet
You should switch to any desktop wallet as soon as possible.
For cold storage or hardware wallet bitcoin core is the best if you are willing to store some bitcoins
Not necessarily. An (currently outdated) example of a nice alternative is Armory.
blockchain can be considered for daily transactions as it is easy and fast
I don't see why Core can't be use for daily transactions unless you really have outdated hardware. Syncing only takes a few minutes.
