Think in that choice I'd go manufacturer item unless someone could indicate why the other would match.

Check the service schedule for the bike too, as often it'll state two oil changes per filter, which reduces cost by half without compromise.  Mainly the oil change interval on these is to cope with fuel dilution anyway, with the filter easily able to competently cover the stated service life Honda gave.

Been using Hi-Flo filters for a few years, they meet the stringent German TUV approval rating if that's anything to go by.
Although on most other critical engine stuff I prefer genuine Honda parts when possible.

I was in Germany for years I remember the TUV as Germany's super strict MOT equivalent, I didn't realise it extended to oil filters.  :o  No wonder so many poor motorists have that sign in the back window that says until the TUV us doth part or words to that effect!

K2-K6:
I view it as a circular argument, if the oil does its job properly, then you dont "need" a filter.

Observing what's trapped in the filter, shows what failed in the lubrication abilities of the oil and system in which it's operating  ;D

The oil is absolutely the primary protection for a running engine, the filter primarily stops SOME of that debris going round the system again,  meaning the oil failed to what was asked of it.

The filter doesn't stop PRIMARY wear, the oil does.

Bryanj:
And what is the only neglected, important part of the system that uses unfiltered oil?

Oddjob:
The oil pump.
