For me, neither! I can't stand the things, sweaty, fussy and horrible! I wanted freedom from such monstrosities!
I now use two different methods to keep dry. My first was to use a rain skirt. My skirt is a rectangular piece of waterproof material, elasticated along one long edge and secured by velcro. Once secured around my waist the bottom edge is about 6" from the ground. The rain falls off my coat, onto the skirt, onto my gaiters and then to the ground. I have the lower edge weighted (bought in a local haberdashery shop) to minimise the problem of the material flapping in wind. I can put on, or take off my skirt in a few seconds, it just sits scrunched up in one of my rucksack pockets waiting for use. I don't even have to stop walking to use it.
My second method is to use a long cheap (£15) waterproof coat, the hem is also about 6" from the ground, again weighted at the hem. Works just as well but takes a bit more effort to put on and off. The coat is very useful when rain keeps coming and going and when it's windy as well, I just keep it on and when the rain stops, I just open up the zip to have the maximum airflow around me. At the moment this is my preferred method.
In the olden days, when I did wear waterproof trousers, the 'trick' I learned from the Walking Forum was to carry a couple of Tesco plastic bags with me, put them over my boots, then my boots through the leggings, no mud or wet inside!
