Scott, Karl, and JJ all have such different styles.
Karl is totally cool with long and awkward pauses but light-hearted, funny, and a little self-deprecating.
Scott talks a lot, comes across as super complimentary and everybody's best buddy. Kind of the exact opposite of his on-table demeanor.
JJ is all business, he's not there for small talk he wants to talk about how Shane got a little funny on this 7 ball, will he settle for the long tough 8 ball or does he pound it pound it to the rail, bringing the miss into play but making the 8 & 9 ball easier.
I do like JJ best, but they are all pretty good in my opinion. This becomes obvious when you watch the abomination that is the Predator and women's announcers. Absolutely brutal
