You can enter MIDI notes in the Piano Roll View with a single click using the Smart Tool. No swiping motion needed. Simply hold down the Alt key on the keyboard and click. Note entered.
I did it that way for a while and still do if I'm doing light input but if I'm going nuts with fills or crazy beats it's just less awkward switching to the draw tool. Then I use the toggle function to either temporarily switch to the Move or Smart tool (usually the move tool) to mess with the feel of things.
Now though I'm using my pad controller more to sketch out drum parts then fill in/correct stuff later.
I haven't done a lot of instrumental MIDI stuff because I'm mostly doing live guitars but I'd still use the Draw/Toggle method or my key controller.
That's just me though... and I'm still finding my workflow.
