Very appropriate comparison categories - it works!
Actually, I think Bitshares and MPAs are so effective and less costly by orders of magnitude... I'm still trying to get my head around EOS, but again, I reckon Bitshares will facilitate that as well.
Interesting how three of the four you mention have Larimer crafting. Also, perhaps a fifth category, Pension Fund and HERO - whats not to like at 5% interest pa?
HERO as in the esports investing / betting?
Nope - HERO as in the Bitshares HERO - Market Pegged Asset created based upon the value of $1USD at the creation of the Federal Reserve Bank in 1913 and appreciating in value at 5%pa, which is about $158ish in 2017 dollars. The purchasing value of one 1913 dollar is actually estimated at around $0.02 today. The HERO is a interesting proposition for ppl that'd love 5%pa - guaranteed and collateralised by a 2:1 BTS ratio - anyway, lots of youtube and Steem advice about the HERO - see @stan. You can also short the HERO into existence. Cheers
