Which oil filter PF48F or PF48E?

[finall]

I have been using a PF48F on my 2007 H2.

GM is now switching to the new style PF48E.

Not sure if I should use that one, or stock up on the old PF48 or PF48F. There is a difference in the construction.

Anybody have experience with these new filters? Are they any good?

I want to keep using OEM AC Delco products for my H2, so please do NOT recommend other brands.

I've been using the 48E with no issues, but I sometimes use Fram too on my other H2.
