i have NI Session Guitarist Acoustic Strummer ; very good samples, you can achieve very realistic sounds, I guess it would be the same with the electric version
The Ujam VG and AAS GS Strum are really inferior IMHO
i've bought Wood And Stone and like it ; it can be use in some kind of electronica (ambient, downtempo, etc.), post rock, experimental stuff or cinematic tracks
You can also try Burier by Kit Plugins, which sounds good at is probably more than only a saturation
you can also look Urban Puncher or FireMaster by United Plugins (saturation + compressor + transient designer)
