Which army has the fewest weapon options when building models and isn’t chaos daemons?

I don’t like having tons of options when building models.

Recently I’ve built a leman russ and I can’t stand how many turret options there are. I don’t mind the ones on the sides and front as they’re easily interchangeable. The turret options aren’t super interchangeable without figuring out magnetization.

Other than that I’ve also built an impulsor and a Sagitaur. I actually didn’t mind the sagitaur as the weapon on top is easy to change out.

I feel the same about the infantry models. Having two options to pick from when building isn’t a big deal, but tons of special weapons and multiple basic weapons gets annoying.

TL;DR: which army has the least weapon choices when building models?
