Yeah there will be bickering like Xbox/Playstation or Mac/Windows type arguments. I have high hopes for both but if it was a contest I'd bet on EOS being ahead years from now.
I'm just going to put all SBD I earn in. Because I have other ways of earning altcoins so no need to diversify. If Steemit was my only method of earning cryptos though I would be splitting it with other alt buying.
