It depends on your style of playing. For example, if you like switching between coil tap and full humbucker, the 5 way rotary offers a faster switching option compared to a 3 way toggle + push pull. And it's accurate too. Let's say you're playing on the bridge and you wanna go coil split on the neck (most difficult form of switching). You can simply use your pinky and twist it all the way to the back full hum and just move it up one click. Entire process takes less than a second when it becomes 2nd-nature. For a 3 way toggle, you will have to switch the toggle from bridge to neck, then pull up on the push pull. Way slower cause you have to manipulate 2 different switches.
Btw, you don't actually operate the 5 way rotary using ur thumb and forefinger. You do it by wrapping your pinky around the knob and twisting, kinda like doing volume swells with a strat.
That said, a 5 way blade switch is still the fastest means of switching but I feel that if you want to go to the middle position it's a little inaccurate.
