The verdict
Buy the Kobra S1 Combo.
8.2/10 vs Neptune 4 Pro's 8/10, and it wins 2 of 5 categories. Best multi-color pick if you want more than 4 colors and can't justify going over $500. For figurines, cosplay parts, and detailed decorative prints, the jump from 4 to 8 colors matters more than the spec sheet suggests.
