Ethereum was captured a long time ago and there is no incentive to make it more decentralized or faster because middle men control staking and validating and make billions of dollars off of this. If you want something fair you need to look into REF on NEAR or Q Blockchain.
It sucks real bad. Ethereum was off to a good start but it defected to the those with a lot of money in the industry (mainly CEXs and VCs). It's a "Wall Street Coin" now. I guess money talks, after all. To say the least, the number of truly-decentralized PoS coins are declining by the day. People are more interested in centralized coins than can be easily shut down by the government at will.
At least, not all hope is lost. We have Peercoin, Diamond, Reddcoin, and a few other PoS coins that are truly-decentralized. I'm yet to try the coins you've mentioned recently. Everything in crypto land is open source these days, so there should be nothing to worry about. Just my opinion
