Of those five models, I use three of them on a regular basis. Orderlies are wk 6, ch 8 are unimpedid, and have a heal. They usually do better than expected in my crews. Guild Sgts give +1 walk to guardsmen, plus flips to wp duels, and can move scheme markers. Really good in the right mix. Mounted Guard aren’t quite as good as Kentauri, but accurately deliver a beater like an Executioner or Thrall, and are themselves pretty mobile and tough.
Exorcists aren’t great. The proxy is terrible. Pistoleros are ok, but are outshined by the new toys. Handlers still need help, as do Death Marshalls. Honestly, though, Guild is probably the strongest it’s ever been in 2e.
