You could say the same things about any lockable hub. The only reason to go with them is what Marlin said about their great parts replacement policy. The bottom line though is that most hub designs have only 1 maybe two moving parts in them, so wear and tear is so low that you would almost never have to replace parts on them. I think in the wheeling community, Aisins are regarded as being pretty bulletproof. Warn and superwinch hubs aren't bad either, just more expensive initially. Most people start out wheeling the cheaper junkyard parts and only upgrade when stuff breaks.
