Philips Norelco vs. Wahl: Which Brand Sells the Better Beard Trimmer?

Usually we take a church-and-state approach to multi-tasking grooming products. Rarely is there a 2-in-1 shampoo-conditioner combo worth your dollar (much less a 3-in-1 with body wash added to the mix). Grooming devices usually fall in line with this rule, too. The best electric shavers focus their efforts on exactly that: giving you a safe, smooth, ingrown-free shave.

Please, what is the best machine for beard and trimming?
Philips Norilco ‎MG7750/49
Or
Wahl 9818 Lithium Ion Stainless Steel ?
Or is there another option better than these options?
