I like ODIN:
https://odinblockchain.org/. It's had some bad luck with the cryptopia hack, so it's having difficulty getting listed on bigger exchanges, but conversely it's still quite unknown. I like that they have actually delivered a product (a privacy messenger with crypto wallet, no phone number required). They have some other pretty good things, like a sweet swag shop:
https://www.odinswag.com/ (3 moon mcafee anyone?). The community is great, and there are weekly updates from the team. It's a long shot, but at least they are doing stuff!
For a more established "altcoin" (token), I like MCO. They have now release cards in the US, which is a big milestone. The CEO is a complete dick, but they have the expertise to get cards with actual use to people around the world. Lots of good perks, like free netflix, lounge access, very high cash back, perfect exchange rates, etc. They have their own issues, just like all coins, but at least they have a huge competent team behind them (like 100 to 200 employees now). With this token, I don't have to worry about the team having no devs, or funding, or any kind of resource, which seems to be the case for most altcoins.
