Personally, I like both equally. I intensively use the 1640/1600 since over 30 years and never broke an ejector blade, spring or screw nor did I ever broke an extractor. I know many did, but it never happened to me.
I really like the 98 too and also use it a lot and I agree that for most people, it's easier finding stocks and spare parts for a '98 than any other action (Remmies excepted). Even if the original design when well executed is almost perfect, some commercial post WWII M98 production is made of modern steel alloys which makes it almost undestructible.
