**DISCLAIMER: Noobs opinion is noobish**
Having only recently got into Malifaux, Lynch is, at the moment, my only master. So far I have found him to be a death dealing monster, either by himself, via his pistol/Final Debt/52 pickup, or by facilitating a face eating behemoth that just keeps coming back. Nothing makes your opponent sadder than to spend 2-3 activations killing Huggy, only to have him come back two activations later.
Between himself and beckoners, they can spread Brilliance around like candy to supercharge the Illuminated/Huggy. His speed can be mitigated by Lure, or Mr Graves "Show him the Door" ability which I have found super useful to get him into positions that may not be expected or to facilitate charges from models thought to be out of range or hindered by terrain.
A well built Lynch crew can put out serious damage as well as work schemes (and deny schemes/interactions from your opponent). His crew does tend to rely on a combo-wombo style of play which may not be for everyone, but for those who like crews that work together as a greater whole, Lynch is awesome.
