It's doubtful you haven't heard him. It's Tech N9ne lol. And while he may not be the best lyrically his songs are masterfully edited and memorable in general. In my book it takes more than just lyrical skill to be the best. Your music also needs to be relatable and catchy (for the lack of a better word). Eminem stands up to this test but most others don't. They tend to use shitty editing software which makes the music sound horrible and is just a pain to listen to. Or they're too hung up on spitting nothing but punchlines and forgetting the entire point of the song in the first place. There are also those out there who just sound exactly the same on every single song they have ever done (drake & Wayne) but they are usually already pretty shitty rappers in the first place.

I was trying to see if he would notice or not lol. Doesn't seem to be a tech n9ne fan.
