This is a difference of 40%. Potentially our votes are 40% more powerful on Hive simply because of this difference. However, it doesn't take into account the huge accounts like 
A test I can run is simply upvoting content on both platforms. On Hive, an 84% upvote with 40k stake creates 0.5 Hive per vote. (67k per 1 Hive) On Steem, an 83% upvote with 26.5k stake creates 0.293 Steem. (75k per 1 Steem). So we see that roughly Hive votes are worth 12% more than Steem votes on a coin by coin basis. This also implies that you get more vests for powering up a Hive coin than you do Steem because there is less competition for them.
I've modified this script slightly to see if it also works with Hive.
It does.
The point of the script was simply to import some basic information on the given account and retrieve the generic information of the blockchain at large
client.database.getDynamicGlobalProperties()
I find this script somewhat interesting because when I created it things like sps_fund_percent didn't exist. The SPS did not exist when I created this code. Clearly the node API was changed to include variables like this during that hardfork.
Even more interesting is that the number of vests you get per coin is pretty much identical on both platforms. Hive has way less vests than Steem does. It was my understanding vests were less of a dynamic resource than that. I guess I still don't know how it works fully. Perhaps 
It takes 5116 Hive to become a dolphin.
It takes 5113 Steem to becomes a dolphin.
Less coins siphoning money from the reward pool means your stake has more power over inflation. The more accounts that have voting power sitting at 100%, the more your vote is worth. The more content that gets flagged, the more your vote is worth.
Maybe one day I'll figure it out.
