Hyperfirm is what I went with because as Ducati stated it's done for you and durable (just add a D ring and maybe some scope details). Also as davej states having something you feel comfortable trooping with and handing to kids, IMHO, is a fit for the hyperfirm. The obvious problem is the accuracy is lower due to the process of making it from a mold versus an assortment of individualized parts and is also not very apt to be modified although some have done it. There may be a waiting list for the hyperfirm right now too, if that affects your decision.
