Silicone is the best palette surface for acrylics.
It is (effectively) nonporous so it doesn't suck the water out of your paint, it cleans fully and easily, it's lightweight, and is cheap as fuck. You can either just keep layering and layering paint on it until its a mess and then flex it and the paint pops right off, or squirt some PVA glue down and slap some scrap paper onto it. When it dries peel it off. The glue adheres to the paper and the paint residue better than the silicone surface, so it comes up with 99% of the surface clean. Just wipe the rest down with some wet paper towel and u good to go.

No spending money on palette paper, no fucking with a big heavy glass plate and razor blades. The only thing it doesn't do is function like a wet palette, but since you can get silicone in hundreds of different shapes and it's RUBBER, if you frequently do start-stop sessions you can just get one with a lid, spritz the paint and place a damp paper towel or cotton ball or some such in before closing it up.

The only people I see who talk about silicone as a good palette are /tg/ warhammer painters for some reason.
