The real choice is silicone versus natural bristle. Silicone is dishwasher-safe and never sheds; natural bristle holds and releases egg wash more delicately, which matters for fine work like laminated dough.

OXO
Silicone bristles are dishwasher-safe, never shed into your bake, and hold up egg wash and melted butter well. Silicone applies glaze less delicately than natural bristle for very fine laminated pastry work.
Norpro
Natural bristle holds and releases liquid more like a paintbrush, favored for delicate egg-washing of laminated dough like croissants. Bristles can shed over time and it needs hand-washing.
Ateco
A professional-style flat natural-bristle brush from a trusted pastry brand, the wide head covers large surfaces fast. Same hand-wash, bristle-shed tradeoffs as any natural-bristle brush.
GIR (Get It Right)
Heat-resistant one-piece silicone with no crevices for bristles or gunk to hide in, very easy to clean. Like all silicone brushes it's less precise for delicate glaze work than natural bristle.
