Health Sherpa seems to provide a quick and easy way to compare premiums by region, but lacks detailed information such as deductibles, and specific provider information. Certainly helpful, but by no means a functional replacement for the requirements of healthcare.gov.
(notice clicking "Apply" sends you to the home page of the insurer, and gives a phone number).
The current system actually contains this information, and probably had a nice view of it, but the misguided people in charge don't want us to see it, despite it all being nicely available in JSON at data.healthcare.gov.
I would not consider that to be a problem still plaguing the site, as poor of a decision as it may have been originally.
