We just recently went to conest from years with Vision EBM. I still think EBM was more intuitive for takeoff. The way I estimate, the very first thing I do is count fixtures/gear, print counts and BOM to get to my vendors. EBM had the best modules for this, BY FAR. Once you enter fixtures/gear, they are labored, and BOM's are produced in one motion, and you are done. In Conest, you don't enter fixtures until you wire them. I hate that. Conest has no way to print reports for fixture counts or a gear BOM.
I do like Conest audit trail, where you are only looking at the audit trail of the breakout you're working in. Conest is more stable, faster and less buggy than EBM.
