I think Thought is the tighest MC out there, or one of them. comparing to common I say there are a few things, BT can be appreciated on multiple levels, one because he is an ill wordsmith, incredible with words, and two because there is always something extra you can get from his rhymes on the hundreth listen. BT is extremely consistent, rarely even a bad few lines. Common, on the other hand, comes mediocre a little bit more often (but not alot). I feel like BT just has more precision, more craft to his style..like it always comes out perfect. I cant fucking wait for the solo jawn. I love common too, but if I had to say, pick one of them for a beat I made(HA!), it would be thought hands down.
