I do neither. I use Subdude platform for floorstanders and Isoacoustics brand stands for monitors. In addition to providing similar isolation, the stands get the monitors off the floor and provide optional upward tilt as needed.
There may be other good isolation products that might provide other options if needed but these are the two I have used and find to both to deliver similarly better results in each case.

You have to make sure to get the right size Isoacoustics stands to fit specific monitors best.
Also note that Isoacoustics are short stands often used on desks, but having tried various monitors on higher, heavy, high quality spiked stands in my problematic room, I find use of Isoacoustics on the floor with upward tilt as needed to provide the best results. There may be other stands available that focus mainly on isolating speakers from floor interactions. Spiked stands alone though solid are also often quite rigid and still transmit vibrations and may not do the job with very lively flooring I have found. Products that isolate well (as opposed to coupling to the floor, which is the opposite of isolating) tend to have some give that absorbs vibrations before they reach the floor.
Coupling is a good approach in some cases where floor interactions are not obtrusive, like in my basement with carpeted solid concrete foundation for the floor.. When floors are lively or built to have some give (the normal case with modern construction to better withstand earthquakes, etc.), isolation rather than coupling is the key.
