After owing 43 P-64-70s since 1968 and two sts Classics, packing some of these daily for months in BCs most remote wilderness, alone, I have an opinion on this.
I handled several of the FN-70s at local shops, don't like them at all and hardly need another rifle. Don't for an instant doubt young Brads word on this, but, the old 70 trigger, while not my favourite for a field rifle, suits me better than the new.
I seldom use any Mod. 70 now, my various custom rifles on Euro actions are better, so are my Dakota 76 .338s and I am now trying my new Kimber MA-.280AI.
I have Mauser triggers, properly adjusted by a Euro-born smith here which blow any 70 away and are the most trouble free of all.
YMMV, but, we all have our preferences and these are mine.
