I still use the glass carboy that came with my starter kit, but everything else goes into plastic. I generally use buckets for primaries and Better Bottles for secondaries (I.e., sours and meads).
I don't use spigots on my fermenters, but I feel pretty confident in my cleaning process for my bottling bucket. I have two spigots. After I bottle a batch I swap out the spigots and throw the dirty one in the bucket when I do my PBW soak. End result is a squeaky clean spigot and my bucket is ready to go for next time.
