A chart on the site compares the plans and what they offer. This feature appears to be the only difference between F and G.

I have always had Plan F and plan to keep it for now. I suppose it may be phased out at some point.

As I recall the only difference in coverage was the Medicare deductible
so if the difference in monthly premiums makes it cheaper to go with Plan G then why not. I think the UHC plans were not that different in terms of total cost based on premiums, you would just be paying more in January to cover the Medicare deductible but less per month for you premiums. I stayed with F.
