Short answer: paint by number asks for a steady hand and some patience with drying paint; sticker by number asks only that you match a sticker to a number. Both turn a picture into a numbered project. The difference is what happens when your hand slips.
How paint by number works
You get a canvas printed with outlined shapes, each with a number, and small pots of paint to match. You fill each shape with a brush. The shapes are irregular, the lines need covering, light colors sometimes take two coats, and a stray stroke means waiting for it to dry and painting over it.
How sticker by number works
You get a board printed with a grid of numbered dots and sheets of pre-colored stickers. You peel a sticker and press it onto the matching dot. There is no mixing, no drying time, no mess on the table, and every dot has exactly one right answer. If a sticker lands crooked, you lift it and put it back.
Side by side
Mess: paint needs brushes, water, and a covered table. Stickers need a table.
Skill: paint rewards a steady hand. Stickers reward reading numbers.
Mistakes: paint means painting over. Stickers peel off.
Breaks: paint pots dry out between sessions. Stickers wait for you.
Kids: stickers are easier to hand over without supervision.
The look: paint gives flat color shapes. Dots give a pixel-art mosaic that sharpens as you step back.
When paint by number is the better pick
If you want to practice brushwork, enjoy blending, or like the smell of a hobby, go paint. It's a lovely way to spend an evening.
When sticker by number is the better pick
If you want a guaranteed result, are buying for someone who says "I can't draw," are doing it with kids, or want a portrait of a specific dog that looks like that dog, stickers win. A Color A Dog kit is built from your own photo, printed on rigid foam board, and uses 10 colors so the face reads clearly from across the room.
