pf or npf?

[Jukka Marin <jmarin%embedtronics.fi@localhost>]

Dear List,

I'm setting up a new gateway machine (NetBSD 7.0).  My old gateway is based
on NetBSD 6.0 and pf.  Can I use pf on NetBSD 7.0 or should I move to npf?
Why?

I have found more examples and manuals for pf, and moving to npf seems like
extra work.  With pf, I could also copy my config over with minor
modifications (I guess).

Thanks for wisdom and opinions.
