In 8-ball I like: usually easy shot after the break. Brainwork is somewhat different and I enjoy those tactical battles in which I need to figure out what if I leave this, he might take that shot etc. In 8-ball I don't like that many times you can pound the rack with a perfect break and still get nothing down. Oh how many matches I've lost at hill-hill with a perfect hit but unfortunately dry break. Practising 8-ball is a nightmare, for me it's just a tournament game.
In 9-ball I like the fact that you need to know all the shots, kicks, jumps, banks and many times you're able to pull the rabbit out of the hat by making a ridiculously difficult shot because it was your only option. In many other games like 14.1, you rarely are forced to take a really difficult shot. But, I don't particularly like 9-ball, with short races and no-call 9-ball, it's too much about luck sometimes.
In 14.1 I like the brainwork, the patterns, the safety play, everything. Being of a pedantic nature, I like to leave the cueball perfect for the second break shot or a difficult rack opening combo or whatever. Small motions rule in this game ! My favourite game.
In 1pocket I like the excessive brainwork, but also the fact that I cannot let the brainwork be the major factor in the game, I still need to make those balls and play those banks and kicks. Also, it's refreshing to be able to try those difficult caroms/kisses/multirail banks. Many of the good 1pocket shots are usually almost useless in other games. One of my newest interests and favourites.
