I'm not sure we can make this conclusion. Certainly the effect you're mentioning does extreme damage but it is localised. Acidification is nowhere near as localised, therefore whilst it doesn't affect individual areas as strongly it is much more widespread. When looking at the accumulative effects the question of which one is worse is up for debate and non trivial to answer.
