It depends a lot on circumstances. If I'm on a day hike I like to use the jacket and pants, if I have my big backpack on then I use a poncho as it covers the pack as well, plus I get a bit hot and sweaty when carrying a big pack and less so when using a poncho (I don't feel the cold, so conversely I tend to feel the heat more)
As for brands I have three different ones I use. In my webbing I have Bundeswehr flecktarn goretex jacket and pants. I also have a Peter Storm interactive jacket that I can zip my fleeces into and lightweight Peter Storm trousers. Day to day I use a German Navy surplus goretex jacket (Best bad weather jacket I've ever had) that has a high fastening collar, a hood that covers your head and lower part of your face, cuffs that seal against the wind, and a storm flap around the hem to stop the coat inflating in high winds. I also have a pair of Dutch Navy goretex trousers but they can be a bit of a pain to get on and off so I tend not to use them
