why do you search for an alternative? i believe blockchain is the best explorer, i dont believe that others dont have any issues, blockchain is the biggest explorer thats why we spot more issues with it
Yesterday blockchain.info showed Satoshi's coins were being moved when all the other block explorers showed they hadn't moved. Somebody must have found a way to tamper with blockchain.info to make it show fake transactions. He might want a few alternatives in case situations like that happen again.
