Solana (SOL):

pro: High transaction speed (up to 50,000 TPS), low fees, and high scalability.

Con: Criticized for centralization and expensive staking hardware.

Ripple (XRP):

Pro: Low transaction costs, fast processing, and strong institutional support.

Con: Facing SEC legal challenges and concerns about decentralization.
