0xMR isn't really competing with Ethereum, it exists on seven blockchains at the same time: Syscoin, xDAI Chain, Ethereum, Binance Smart Chain, Polygon, incognito chain, Near ProtocolThis is interesting. I will have a read up and look into it, however competing with ethereum has proven and will always be difficult to do.
I think dot have a good platform allowing integration with eth rather than trying to topple it.
The price is looking inviting though with 0xM, maybe worth a punt on, with long term gains in mind.
