Yeah, I guess that it is difficult to model a true steel string sound and I've not explored much of the latest Strum to hear if things have improve. Which sound a bit daft of me. But the main reason I have opted for AAS Strum over sample libraries, is I try to stay away from sampler stuff.
The only sample players I do use is Battery and BFDeco, but I also use Drumaxx, which uses physical modelling, like the AAS products.
If I do have to eat my words with regards to using samples, it will only be because I'm creating my own guitar samples...
Also, and I might have mentioned this earlier, I am usually putting Strum through either GR5, TH2 or something like Saturn, so I'm not too bothered about the Strum sounds not coming across as "real."
That Hummingbird sounds the woofs nuts, but I'm still saying "no."
