It’s been a while since your post, so you might have already made your selection. However, from the casual research I’ve done on watercolor related media like markers, Arteza water based markers seem to work well. It just takes a different sort of technique for a “good” piece.
There are also Koi or Windsor & Newtown seem the most true to traditional watercolor pigments. I have 2 W&N markers myself and though I don’t have any real application for them besides maybe monochromatic value work (I didn’t purchase any cohesive colors, just a brown and an indigo that I like the look of), I do like them for a sketchy thrown-together looking drawing.
