[J-S-Q]

I use my S3 for plugin control with relatively simple plugins. e.g. It's perfect for adjusting Threshold/Ratio/Attack/Release/Gain on a compressor but for super in depth plugins with dozens of parameters I would use the mouse. I guess for anything that fits on one page of the S3 I will use the controller.

It helps hugely if you can rearrange the plugin parameters. e.g. any time I open a compressor plugin, knob 1 is always Threshold, knob 2 is always Ratio etc. This makes it much more intuitive.
