The pill was originally introduced, ca. 1960, in doses as high as four mg. Today, they run between .25 and 1 mg. All of today's are low dose.
Taken as directed, all pills, and other hormonal systems, are equally effective. The only advantage to the "stronger" pills would be that they have a slightly larger margin for error. All today's pills have a margin for error of six to eighteen hours in the "average" woman. They would also have stronger side-effects. Today we also use combination pills so the dose of estrogen is no the only consideration.
You are a big girl. Why ask someone else to do your research for you. Look up oral contraception and you will find dozens of sites showing exactly what you are asking.
Unless you are having side-effects, there is nothing gained by comparing the dosages. If you want a low dose, use the Nuvaring; if you want a high dose, be prepared for trying several pills until you get one you can tolerate.
