The best knife sharpener. Chef's choice or Master Grade? - chefs choice sharpener

I cut the meat and the use of knives, Forschner Granton. I wonder what is the best electric pencil sharpener: Chef's choice of 130 or MasterCard. If there are other better than these two please let me know. Any contribution is welcome. Thank you.
