There are advantages and disadvantages... for example the (10%?) inflation in EOS goes to miners who hold the RAM and other Computer Equipment. In Steem the main part of the 10% inflation goes to authors.
This is something that I think is very important to consider.
The very basis is somehow different, and if you build an app on that you will have to hold more and more EOS while your app grows in transactions. If other application grow even faster, the price to run your application might rise disproportionately.
Inflation of EOS will be 5% maximaly. Its flexible.
Steem will have 1% fixed infl. to forever. ....eventually. Im not sure how much is it right now, 9%?....
Will you? Network capacity will grow with token price. Miners will have to expand accordingly to have enough storage.
If your app grows - you make more money (this is up to you), you can afford more EOS tokens. If it doesnt - you dont need more resources. Quick maths :D
