If the paper wallet and the desktop wallet will be compared . I will prefer the desktop wallet because the paper wallet is not secured especially on public areas like market and other public areas. Compared to the desktop wallet it is electronic and it is so hard to be stolen, so for me desktop wallet is more advisable.
I agree, having a desktop wallet is much better than having a paper wallet because you can load the desktop wallet at any time if there is a computer nearby with an active Internet connection. Paper Wallets are usually for people that prefer to keep their money safe by burying it in something or hiding it somewhere though in most cases if someone finds the Paper Wallet then the money is good as gone.
Desktop wallets work best with a password, of course.
i think beside of desktop wallet, i will use android phone wallet because if i am out from home and i need to buy something like to refill my phone card, i only use my android phone to buy in local store and i can pay with the wallet on my android phone. using desktop wallet is just for saving my most of bitcoin so in my android phone, i only send some amount that i think its enough for my to buy something later.
