The ability to send money in one click is both strength and weakness. This means that you could send millions of dollars by mistake and hackers could also steal them without any obstacles. With banks you would be contacted by them if someone tried to move a large sum of your money.
With Bitcoin, the pros are you have your keys and you don't have to rely on governments, banks to broadcast your transactions. If there are miners on Earth, you can choose fee to include your transactions at tip of mempool. Your transactions will be confirmed by miners if the fee you give them is on tip of mempool.
Nobody can seize your Bitcoin if you don't leak your private key.
