Killer choice advice

EDIT : Thanks everyone, I'll go for him as soon as possible then ! Zombies goes brrrr

Hello,

I'm about to buy Nemesis as I like the zombie gimick of his kit and just like "pet" overall.

I was wondering if Houndmaster and the Knight would bé better for type of gimick ?

I'm a newbie, played some survivor and start to get décent, or almost. And have only some game as légion on killer. So, Is Némésis the good idea or one of the two other would bé better/less difficult for a noob ?

I value easy to use more than how strong/meta a killer is, I don't play enough to hit the skil curve anyway.

Thx for your time ! (And sorry if m'y english is clunky)
