The 7-GUIs suite looks better, but so far only one JS framework implements it. The problem with more realistic benchmark apps (or suites) is that they require more effort to implement, so you have a selection bias towards easy-to-implement yet too-small-to-be-useful demonstrations like TodoMVC.

Something like a GmailMVC would be better.
