Both are superb guitars. I wasn't sure how to vote because I prefer some aspects of both guitars. I owned an 0M1G deep body which was an outstanding guitar. I strongly prefer the deep body option with Mahogany rather than EIR. Just seems to me that the EIR doesn't need it. The deep body produces more low end and the EIR already has a lot of bass. I think the regular depth provides a lot more clarity in sound, even in Mahogany. So, it kinda depends on what you want.
I prefer German to Adi because I play almost all fingerstyle and German is a little sweeter a sound. But if you're going to play bluegrass with a pick, Adi is probably your choice.
My guess is that there isn't a bad choice here. Good luck. Great guitars.
