please quote me if i am wrong.
but i think the quality ico projects still love etherem,... because ethereum is in there minde the most trustworth system.
maybe its now not that far than other platforms.
but it is (when i am not wrong) from the algorythm which is provides the most secure one (after bitcoin)
eos is fast,... (and i am as well holding some) but with the 21 nodes,... there could be some problems with the voting.

and the erc 20 standard is nowdays that common that it is easy for the people to join.
thats my point of view
