wasn't there some eyewash back in the day
about how a cup of tea actually had more caffeine in it than a cup of coffee. Can't quite recall.

That is eyewash
Tea leaves have more caffeine by weight than coffee beans, but it takes more beans to make a cup of coffee, so coffee is (in most cases) stronger than tea
