I doubt you would see much difference in IQ between the 80-200 and the 70-300. Maybe some lower flare from the newer lens but under rainy conditions it will be small to zero.

The AF item you mention happens with many/most/all AF camera and lens combos that I have used. The first few times I really noticed it was with the D3 and my 70-200 AFS VR and I thought the lens AF motor was going bad on me. Then I worked out the how and why and nowit it happens I manually turn the focus to infinity or focus on a distinct high contrast edge.
All technologies have limitations and weaknesses.
