Taimanov vs Kalashnikov Sicilian
Playing the Sicilian, means you have to do the leg work on understanding why moves work or they don't in different variations. With the amount of transposition to different lines in the Sicilian you may find that you often go into different variations based on what is best against the move your opponent played and not what is best for your style.
I think multiple systems with a6 are very easy to learn and (imo) very fun to play.
If you want to play either the Taimanov or the Kalashnikov, it's hard for me to be unbiased, since I am studying the Kalashnikov, but you can play either. I played the Taimanov with very little success as well.
I don't know your skill level, but if it is about 1200, I suggest you don't play these openings. They're too complicated for people who are new to chess, and you will not get what you 'studied' on the board.
If you want to get better, play easy openings, like the Scotch, Scandinavian, East Indian etc.
I actually saw that from GothamChess in today's candidates (I guess he read that article before posting the video), which made my passion for this opening revive.
I have played a6 systems multiple times (not always with the same move order or emerging from other second moves from white. In fact, I used to play the Kan and the Najdorf when I was not very good, and also the Drazic.

Im 1200, but i heard so many opinions on that already. "You should play main lines/You shouldn't play main lines/You should play gambits"etc. I know that it's with good will, but at this point I just play whatever looks cool.
