I use blockchain wallet its very good to wallet online and i think is the best wallet online and also xapo i like to use it because no fee for sent bitcoins.
you can not compare between blockchain.info and xapo
blockchain allows you to get your private keys. xapo is just like paypal
agree with you xapo is like paypal but no fee
xapo is best wallet if you confused about how bitcoin works
i think xapo is good wallet because xapo is member of bitcoin foundation
