Having been to both multiple times, and with the context that we support both and have a presence at both, and think both events are great for different reasons, I prefer Bronco Safari. Reasons below:
Creature Comforts: Moab, by nature, has many more food, coffee, and hotel options. Tons of great food and drink options, numerous coffee shops, local shops/stores, all major hotel chains have a presence to suit a range of budgets.
Off-Roading: I prefer the off-road options in Moab. There is much more variety both in terrain and difficulty than in Colorado. Also there is a wide range of duration. Some people wanna spend 2 hours on the trail, some wanna spend 12, Moab has it all and a lot closer to town where at Buena Vista you are more limited in trails and they are farther out.
Other Activities: Moab has a ton of non off-road activities to do if you are looking to explore more. Hiking, national parks, rafting, sky diving, mountain biking, horseback riding, etc.
MBS is heavily focused on off-road drives where as SCW has a much higher emphasis on the vendor show in the field, for that reason I prefer MBS bc I can choose from 10+ drives a day to go on ranging in difficulty from 1-10.
So if I didnt have the job I have and was driving that distance for one event, I personally would choose Moab Bronco Safari. Hope that helps!
