Silicone cases are soft-touch, grippy and great at absorbing minor drops — ideal for everyday use, though light colours can pick up stains over time. Leather (or vegan leather) feels premium, ages nicely and slims down the profile, making it the go-to for a classy, professional look. Clear cases show off your phone's original design and colour, and modern ones resist yellowing far better than older TPU.
Quick take: choose silicone for grip and daily protection, leather for style and a slim feel, and clear if you want to keep your phone looking factory-fresh. Whatever you pick, look for reinforced corners and a raised camera lip for real-world durability.
