Paint Pen Smackdown!
I recently got some acrylic paint markers by Montana, and wanted to compare them to my Posca ones. Both are water-based for easy clean-up, and to be honest they are very, very similar. Here's the Montanas...
They are new to the market, and based on their popular "artist's" spray paint line. In theory they are a 2mm line, but as you'll see, they act more like the 1mm line of the Poscas....
yeah, there's no colors noted because the writing on the pens is all Japanese.
Both types are high-quality, don't bleed through paper (looking at you, Copic markers), and have excellent coverage. They are almost opaque layered over each other, with just a hint of the under-color showing through.
"M" =Montanas, "P" = Poscas - the flower is all Montanas, and you can see the yellow flower centers pretty much cover the blue.
I did this just to compare the colors, and you can see that sometimes the Montana's blurped out a fat line, but usually it comes out fairly fine. The control over a detailed pic would definitely be better with the smaller tip of the Poscas. Both types of pens come in multiple tip sizes, so you could just buy fatter/thinner if you like, but this was considered "fine" size by both.
They work well on slick surfaces (glass, plastic, etc.), but I usually use them on paper. They will blend nicely on glossy paper, but not so much on watercolor paper, so it's a flatter, more cartoon-y look.
Why would you use them instead of ink markers or gel pens? Because they are much, much more opaque, and can be cleanly layered over each other. They really "pop" off the page because of that. Painting over collage work or photos is a breeze with these. As to which to chose, go with the brand that you like the colors of better, or are cheaper. I generally get pens at JetPens, a mom-and-pop business with great service and huuuge selection of off-beat pens.
So there you go, the acrylic marker smack-down ends in a stand-off: I'm calling this one a tie.
