I avoided the JD walk-behinds because they seemed to be the "entry level" big-box equivalents that so often don't carry the same quality as their larger, reputed counterparts.
Honda is all over the big box stores and IMO is targeted towards the homeowner and that use cycle. I've owned two honda walk-behinds. as someone posted above, they are not overbuilt, but built enough. The machines do better with savvy maintenance, though the engines seem to run no matter what as long as they are fed clean fuel.
Like any other machine, they require some care. My ex has an 8 year old honda hrx17 or somesuch. it never gave me any trouble, but several years without maintenance and my son says its starting to have trouble.
I have a newer model and it is typical honda. starts easily, has decent power, the handles don't break off, but I do have a hard time keeping the blade sharp.
