As long as Block.one markets it well, makes it easy for developers to develop on, as well as normal people to use its dapps, it should come out on top. That's my opinion on it. The head engineer seems to be one of the few geniuses in the industry, as he's already built 2 very successful blockchains, and he's building EOS for him to develop on. I also think he wants to prove Vitalik(Ethereum founder) wrong on his direction for Ethereum, which might help EOS's marketing. Time will tell. I plan on soon developing/testing on EOS during its ICO to have a head start for when all the bugs are worked out and they improve the blockchains performance for the real scalability it's promising.
