Real Guitar is my go to plug for acoustic guitar. Indiginus acoustics a distant 2nd.
Real Guitar just seems to sit well in most mixes.

It takes a while to acclimate to their velocity settings as they are different from most guitar plugs. Once you figure them out I think you'll agree that Real Guitar is one of the best of the bunch. I tend to vary my velocities in the 60-70 range. Everything sounds natural in that zone. 80-90 for harder notes.
Real LP is great but I rarely use Real Strat.
