Depends on how much you are storing.  Each has it's place.

Hot wallet is good for holding a little cash for spending if you need it.  Don't put a lot in it.

Cold wallet is good for holing your BTC offline and is safer.  You don't surf internet, etc with this on a computer.   Keep it on a paperwallet or usb. (Have a extra copy aswell).  Be careful where you store the copies.

Blockchain wallet is better than Coinbase wallet ? Please help me for that question !

IMHO yes. For coinbase, you don't have your private keys, and so if it goes down, you will lose control on your bitcoin.
For blockchain.info, you can make a backup of your wallet and can import it in another wallet client/service at any moment.

Blockchain is always sync ? Can we transfer BTC to a exchange any time ?

Blockchain.info do have some occasional downtime.

I disagree with you, but only somewhat.   
If you are in the USA:

1)  coinbase must be one of your wallets.-----------  2 coins.
2) blockchain.info  is a good wallet. -------------------------------------------5 coins.--  2  wallets each with 5 coins

3) 2 different exchanges.--------------------------------------------------------3 coins.---  each exchange with 1.5 coins

Above are not the exact amount of coins but more like the ratio of coins in each place.

Below is for the lucky that thought to buy and hold when coins were under 10 dollars.


4) a  few cold wallets only if you are heavy duty holder of coins.---------------------some crazy number 2000 or 3000 coins .
