Great question!
It might not be reasonable to expect a project that is less than a year old to already have as many applications as one that's three years old. But there are far more dapps being built on EOS than already exist on Steem. It's not even close, actually.
Consider:
EOS already has better wallets and a larger community, and it's not even a social site. Steem is largely relegated to being a social application, without the contractual and business applications that can be as readily built on EOSio. EOSio is endlessly scalable.
As for blockchain activity, Steem was solidly number 1 about a year ago. Today it's number six, with two EOSio projects (including EOS) ahead of it. EOS is solidly number one, with well over 21x as many transactions as STEEM. Even BTS has almost twice as many. http://blocktivity.info/
Don't get me wrong. Steem is great, the community is fantastic and I enjoy building on it. But to compare a three year old multi-million dollar social project that took over two years to develop mature dapps to a <1 year old multi-billion dollar one that already has multiple business dapps and sidechains, plus at least three social sites being built on it right now, probably isn't a reasonable comparison. A year from now it won't even be close, as EOS adoption already vastly outstrips Steem. Marketcap aside, simply look at volume traded and transacted.
STEEM maximalists will likely be disappointed. It's a great tool. I doubt that it'll never even be in the same category with EOS, TRX, TLOS (which has gained surprising momentum so quickly) or ETH, among others.
