Can anyone please explain the difference between ethereum vs waves and Omni. Marketcap wise there is no comparison but other than that what are the difference. How is ethereum better than there two other platforms and others that are in the market.

Also is waves second in this market or some other coin. Omni seems similar with tether maidsafe and synereo using it it but don't know why it is so undervalued.

Some clearification would be appreciated.
