As far as i know :
- Failcoin, because their chief is a friend, and he really loves his project, plus they have a great dev.
- Aquarius because their dev is active, really active.
- ETH because they are active, even if they should review their priorities.
- Lisk because they release updates on a steady stream.
- Waves like Lisk
- BTC because it is constant updates, you can even have a live feed at the bitcoin-core-dev IRC chan.
I don't really know for the others, but most of the coins have an active development team, except te scam coins, shitcoins ...
why no one care about spreadcoin, it's a wonderful project and it's receiving a nice addition with master nodes, so add spreadcoin/helium to your list, and pascalite have a nice dev that is a miner and now his shit, better than many dev here
