My favorites are Cosmos (ATOM) and Ternio (TERN). I use ATOM for my long term holdings and Ternio... well, let's just say I've got bullish hopes for the small-cap TERN tokens. I stake them in order to earn cash back when I use my Blockcard. It isn't a set %, but I don't spend very much so getting 6% cash back actually does probably equal more money than a 10 or 20% APR would, simply because you're only staking $1k or so worth of tokens but you can earn up to $300 per month just by using the Blockcard instead of a normal debit card for expenses.
