In terms of the price?
My basic framework is: the coin with the best development team + most infrastructure (e.g., exchange support) + best reputation will have the highest price. For now, transaction speed is not as important, but that could change with wider adoption.
I gather that bitcoin's development team is stacked with talent and its devs are mostly in it for the long-term, so perhaps that's promising. I've followed the blocksize limit debate a bit and it seems the bitcoin team has solutions in the pipeline (lightning network).
But there are clearly some tradeoffs between the commercial/transactional viability of a coin and its decentralization. For example, Bcash is trying to distinguish itself by sacrificing decentralization for speed . Its supporters are also muddying the waters by calling their project "Bitcoin cash", taking over the bitcoin.com domain, taking over r/btc, and so on. They've had plenty of success, but until cryptocurrencies are widely adopted for commerce I don't see them having a big advantage.
Let me know if I didn't answer your question or if I was otherwise unclear.
