I like Myriad (XMY). They just implemented Argon2d mining along with the existing sha256, yescrypt, scrypt, and myr-groestl. SHA and yeacrypt can be merge mined too. You can mine with easymine and pokemongomongo pools.
XMY is down 98% from the peak levels, and it is showing no signs of recovery. What is the point in mining a coin, if it ends up without any value. Also, the only exchange in which it can be traded is Bittrex, and there the volumes are quite low.
My choice right now is BiblePay. It is easier to mine, and the value (in USD) has increased by 125% during the last 30 days. But once again, exchanging this coin to BTC is an issue. Right now there is only one exchange that supports BBP (SouthXchange).
