What live implementations are using POS (Poof of Stake)? It's all academic and likely to be only marginally faster without a lot of risky optimizations.
Lisk, Nxt, Bitshares and dozens of others.
From what I'm reading Lisk only supports 25 transactions per second.
Nano/Raiblocks. Mainnet has been pushed to 300tx/s - theoretical max is 7000tx/s - Wallets available for all platforms.

Is that what happens when you accidentally lock yourself out of your crypto wallet forever?
