It’s not a “one size fits all” answer. It depends on what state you live in, as well as different states have differing rates for the same exact plan. If you want to pay a higher premium and have less co pays (or no co pays), you can. If you want to pay the least amount, then a high deductible plan may be suitable for you or you could be somewhere in the middle (more and more people are gravitating to this approach).

You can’t get MORE benefits moving from one company to the next unless you change the plan letter (example: moving from plan N to a G, or High Deductible G to a regular low deductible plan G.)  Also, a plan N is a plan N, a plan G is a plan G no matter what company you go with. The federal government standardized the plans in all but 3 states. Think of an industrial bakery baking thousands of loaves of bread with the exact same oven and recipe. Each grocery chain will put it’s own bag on it with their own label and sell it for a slightly or sometimes big price difference. The same concept applies to Medicare Supplement plans.
