I use a lot of different beaters with my NB. Have tried pretty much all of our options out (except for Mature Neph as I don't own him).
Nekima is obviously great, but she really isn't always the best choice. So Teddy comes into a lot of my Dreamer lists and occasionally with other masters. Hooded Rider is excellent, especially with Quick Murder in the pool. I also have really been enjoying the Strong Arm suit lately. He is quite tough and brings you strong combat and decent shooting. Has become a core part of my Zoraida builds lately since she really can't afford to lose her beatsticks early. Also McTavish is INCREDIBLE. Especially with Doppelganger. I'll often use those 2 and a waldgeist to go off apart from the rest of the crew and take care of an area in games like Recon/Interference where you need to spread out your crew. Also I find I don't tend to take beatsticks as much with certain masters like Collodi, where Stitched are your big hitters.
We have loads of good options though, so just try them out and see what your personal fav is.
