there are many blockchain explorers out there , buy my favourite is
https://blockchain.info/ , becuase its the oldest one, and dont have much distracting ads on site, and site loads very fast.
other than that, it shows btc amount in USD also., so it helps me to understand how much of transaction worth of in USD and i dont have to go to google and do xx btc to usd.
plus they have their own wallet system , i like that too, you can create as many wallets and each wallet can have unlimited receiving addreses, so nobody knows who is receiving the funds.,
when i first came here , i created a thread for asking how to create site like blockchain.info as i really liked that site and wanted to start something simmilar,
