You are so right, once you begin to ask around for suggestions for the best front end it appears that there are 567 more in development and ten more in beta that you hadn't even heard of. I must confess that as a technophobe who is being educated on this stuff very, very slowly I am often at a loss on the nuances between them.
However it seems obvious that a front end to access several chains seamlessly would be a priority. I remember masdacs looking like they would develop in this way but didn't quite bring the idea to fruition. I believe there are so many similar opportunities as yet un-tapped in other areas of the same ilk. Sooner or later somebody is going to 'clean up' by filling the gap.
I do believe we are heading in to a golden-age of blockchain development, the answer to prohibitive costs could be offset by a blockchain based, crowd-source funded project IMO.
Kudos on asking the right questions my friend, this has the potential to trigger the right mind to action in order to deliver the right answers. Have a great week :)
One day I think we will see block chain browser wars like in the old days of Windows explorer verse Netscape.
