I do think that Monero is probably the best altcoin right now, since it actually does something major that Bitcoin doesn't, even if its scaling is terrible and it'll probably be replaced by a Bitcoin sidechain someday. Achieving Monero-style anonymity for everyone should be a long-term goal of Bitcoin.
Thought this was interesting to read.
theymos' position on Bitcoin scaling is well known so I am not surprised at his comments on Monero scaling. I completely disagree with them though. He does to his credit see the value in Monero's fungibility, privacy and anonymity.
