A sliding cue ball is the single most important shoot in pool to master.
Spin introduces several other factors into a shot like swerve, throw, deflection and those factors are directly influence by other factors like cleanliness of the balls, type of cloth, etc.
Now I am not one to say you should never use spin, but I am one to ask why introduce a lot more variables into a shot than you have to? Can you master all the variables in all the different situations to use spin constantly and successfully? Absolutely, but a vast majority of players are not going to so they are doing themselves a disservice by not sticking to vertical center as much as possible.
Using the tangent line is much more reliable as it has a lot less variables to change the cueball path and thus it is much easier to master and use consistently by even lower level players that understand the tangent line and how speed and high low affect it.
I would say that unless you have mastered shooting only on the vertical axis, then you should only be using spin when you absolutely have to and then, you should minimize the amount to only what is absolutely needed.
Right and left should be practiced just like all the other specialty shots like using a bridge, jumping, masse, shooting off a rail, shooting over a ball, caroms, bank, kick and combos. Then in the unlikely case that you have no choice but to spin you are equipped to put a valid effort into it.
