My apologies on this: I thought it's the gear oil (GL-4 vs GL-5), confused with motor oil spec API GF-5/GF-4.
For motor oil, I like GF-5 better. It's a much more improved, all rounder so long as your engine is built to support it (roller cams, etc.)

Having flat tappets/buckets/lifters is not a death sentence.
It is only if they are highly loaded that there is a problem with modern oils. This generally means only some high performance cars [usually older models] or hot aftermarket cams.
Of course, break in is always a consideration.

What standard is more stringent? ILSAC GF-5 or ACEA A1/A5, B1/B5
I use two different M1 5w-30 oils. HM is GF-3 and the EP is GF-4 but they both meet ACEA A1/A5, B1/B5
I have heard the ACEA is a more stringent std.

depends on what year the ACEA is based on
