However, its a question of how well they work as they age. I wonder if a mechanic with a scanner would say your o2 is "healthy" or not?
as a macanic i can say that when a o2 gets "lazy" it dosent switch from rich to lean and vice versa fast enough. when they smog your car, they hook up a DSO or digital storage ocolascope (o-sill-a-scope) and can see how fast it switches. obd0 / 1 is 100ms and obd2 is 75ms.
on a side note do u recomend the same as honda uses (ngk?) like this one:

When I replaced the O2 sensor in my old Dodge Spirit I cheaped out and went with a Bosch. It crapped out after 40,000 km...the OEM one had lasted around 260,000 km.
I've heard this is relatively common. OEM components just seem to last longer than aftermarket in my experience (I had the same issue with some Monroe struts compared to the OEM struts from Dodge - OEMs lasted 3x the distance).
