Restylane or stylage? Or something else?

Dear reader I want to get lip fillers and I can choose between the products restylane or stylage. Now I really don't know what's the best product and the difference between the products (or is juvederm much better)? My priority are natural lips. Could you help me? And how is the pain if they don't use nerve blockers but just lidocaine creme 12%? Thank you and I'll hope you have a answer.
