From a user of EOS, ETH and STEEM.
I have played with all these coins, and others, but this are the the platform likes :)

• From ETH I got no engagement at all... i just used it to participate in ICOs.

• From EOS I have EOS Knights ... playing games.

• I haven't tried TRON yet.

• From STEEM I have social engagement, blogging, reading ..... I have delegations to more than 5 projects, I use more than five different dApps, utopian, dtube, actifit, steemhunt, dlike, partiko ....gaming with steemmonsters ....

Talking about user engagement :) .... STEEM is by far the richest platform!
