I had both (had two Shuttle 3.0s at one point) and spent time running them right up against each other.
The Shuttles were better made and had better support but the tone of the GK spoke much more to me at the time.
Shuttle 3.0 - cleaner, more versatile, better service/support at the time (probably even now, thanks to Agedhorse's involvement).
MB200 - LOVE the tone, very baked in tone. Suffered electrical death due to ther wrong instrument cable touching the wrong speaker cable. Always had a bit higher noise/hiss.
I struggled to get a sound I loved out of the Shuttle while it came super-easily with the GK.
I still have an Genz 8T extension cab that I use for practice or acoustic sets with my Quilter Bass Block or the Tonehammer at low volumes. Consider it an additional character reference for the quality of work GB was doing at the time. It's awesome.

- and prized by acoustic players for its accuracy.
