Don't think to verify a transaction 60 seconds is too much when XRP, Steller and other take less than 4-5 sec? When we all need more transaction with less possible time then it's might a disadvantage.
An XRP transaction takes 3-7 seconds to process and over 2 minutes to get to a solidified state. Ripple is a centralized system, so it is a disgrace to process a transaction so long. For a centralized system, a transaction should be below 1 sec if considering high volumes and less than 80 millisec at the current state. They do not have a consensus, so basically, their servers only process transactions. I wonder what would happen if they switched to decentralized? They would process in 6-9 hours, worse than Ethereum. Moreover, if you compare their servers' power, you would question why their system is so slow.
A Stellar Lumens (XLM) transfer takes 3-5 seconds and 3-4 hours to get to the solidified state. Recently, blockchain-powered network Stellar stopped confirming transactions for more than one hour, effectively going offline. Stellar's major issue has now been highlighted publicly: The project is not decentralized, at least not to the extent expected at this point.
An STB transaction takes 3 seconds to process and 56 seconds to get to solidified state.
