STEEM is obviously the one I use the most. I use Steemit/Busy, @dlike @steemhunt dpoll and @steemmonsters the most. I never post articles on STEEM. Instead I use Busy because of the free upvote.

I've never used Bitcoin other than holding some on an exchange. I use Dash or when that isn't possible, I use Ethereum. Both are fast and has ultra low fees (especially Dash)

I've used Bitshares a bit and https://soundac.io (A DPoS music streaming project) occasionally.

I haven't tried Augur or CryptoKitties. I've been very impressed with Byteball and I've used several of its smart contract bots such as the lottery. It was a pretty decent for a crypto project. Supporting World Community Grid for medical research and earning Byteball is really nice. They have daily payouts. It's a great way to help humanity with your idle CPU/GPU power: https://steemit.com/byteball/@vimukthi/byteball-leads-world-community-grid-thor-challenge-2018-with-the-power-of-incentives

Does using Brave browser count as a DAPP. It's an amazing project and comes with a crypto wallet and great privacy features. I've also tried https://lumeos.io and several other obscure crypto projects just to try them out. I've also used Waves DEX which isn't as great as Bitshares.

I also tried BitTube when you asked about the project to get a feel of what it is. I also checked out https://lino.network when Dlive migrated. I didn't think it was that great.

That's what I remember from top of my head.
