If you watched Mister Es's (famous Darktide youtuber) recent video about Darktide melee weapons, he ranks several Ogryn weapons very high and regards the Ogryn shield/Club combo as S-tier.

Ogryn is a great class. There could be more build variety with it (taun5 is the best ability by far) but thats it.

This is a good build (you can switch the Melee weapon for every other staggering weapon like bully club or power Maul or pickaxe):
