Looking at my standard template I tend to use stock units and REs mostly for utilities and simple effects:
Flower Audio Loudness Meter - A device that should REALLY be unnecessary but Reason doesn't have simple audio level readouts anywhere so suck it RS.
Reasonistas Sidechain ReAction Enveloper - It's like LFOTool, but no annoying popup window since it's a Rack Extension. Nice.
Uberwave D-filter - Very steep and easy to use filter unit for whenever you want to really cut something away. Which is always.
M-class Stereo Imager - Never mind the stereo. It makes your low frequencies mono bro.
The Echo - Simply a very good delay unit. Drag it into your channel, default preset, adjust dry/wet and it's good to go.
For synths and more complex effects it's mostly VSTs these days.
Edit: Also Umpf Club Drums - It has all my drumz in it (wait, not the REX loops.. oh heck that's 7 devices now including octorex)
