there is specificity instead of vagueness:
- It looks like the payment support for people whose income is to low to afford insurance is tax credit...which is fine as long as the individual has enough tax to cover the insurance cost he/she can't afford. Otherwise, how would this work? And of course from a cash flow standpoint, there is a timing difference between receipt of the credit and paying for the insurance

- Promotion of health savings accounts, which of course already exists and has little to do with what the ACA was designed to address.

- encouragement to small businesses and individuals to band together to form larger insurance pools. Which also already exists outside of the ACA.

Otherwise its just a bunch of flowery language that does not address the central questions:

How do we provide affordable access to health care? Just because his plan says they won't let insurance companies deny coverage of pre-existing conditions, that does not address the affordability half. Affordability requires some combination of getting more healthy people into the pools - which is the same struggle the ACA has had - and support for lower income people.

IMO, their plan apes parts of the ACA, and where it doesn't there are HUGE holes in explaining just how it will address the issue of accommodating the 20 million people relying on the ACA for coverage
