Help me understand rebuild vs crate?

Blueprint is an awesome company and we are lucky enough to have a member of their management team active in here. If you go crate, theyd be my only choice. The fear of murphys law is what would make this decision easy for me. I have built plenty of engines in the past and one mysterious bearing failure on one i did myself, and that was enough to lead me to a dyno tested offering with a warranty from now on. I suppose if i had built 25 myself with zero issues i may be on the fence. But then looking at the cost of machine work and parts would steer me right back to blueprint.
