i'd say decent. they are actually disrupting the drm domain as far as i know.
stratis seems solid since its a realworld company connecting both worlds... but there are several like that.

then there are a whole lot of bitcoin 2.0 chains all having already solved bitcoins shortcomings but none of them seems to get real traction.
seems like bitcoin with its shortcomings, although actually being tackled this month just has the best PR bitcon can buy so no reason that would really change..

gamecredits has a cool concept and could be a candidate for world domination when it comes down to in app/game purchases.

lbry/ steem seems interesting but still lack any real headlines.

what i mean to say is that you just should classify every coin in its own respective field of play and then you are left with ordering them with a simple formula like potential value + actual momentum created so far + trust

so e.g.:
pure payment/transaction systems:
- bitcoin, litecoin, zcash, monero, ripple, dash ...

alernative proof of X solutions
 - burst, ...

Smart contract/ framework systems:
 - eth, lisk...

Content distribution/ social media systems:
- steem, lbry, decent, ...

asset tracking systems:
- iconomy, melonport, ...

blockchain integrators:
- stratis, bancor, ...

data storage
 - sia, storj, maidsafe ...

prediction markets
 - gnosis, augur

distributed computing
 - golem, gridcoin, ...

venture capitalism
- vslice, tha dao, ...

iot blockchain
 -  slockit?, ...

in-software purchases
 - gamecredits, ...

Scientific Learnings of World for Make Benefit Glorious Race of Humanity
 - curecoin, foldingcoin

tipping/rewarding systems
 - dogecoin, ...



so that.


anyone care to improve on this basic draft?
