Well, honestly, the only pill I could truly say was "good" was the tan/brown Pisces I had sometime around July/August this year. Keep in mind that I've only been rolling since February of this year.
In any case, I've never had such a wonderful experience on a pill. The roll completely floored me, I wasn't tired but not speedy, I had the cleanest euphoria I've gotten from any drug and it was the only time that I came down from a pill and fell asleep within a half hour. Hell, I even got hungry and ate when I came down!
It certainly wasn't the most fucked up I've ever been. Not by any means. But being fucked up from a mixture of meth, caffeine, and MDA is not what I would call a good roll. The come-down from the Pisces was so smooth, not even a hint of depression the next day... the come-down from my two of my strongest (single pill) rolls ever, red Cupids and green Ladies... not so pleasant.
