well the (top two) sealskin and carcover.com look like 100% waterproof covers and in that case outdoor covers. I believe you want a cover that breathes.
The Weathertech specs read as an indoor cover only and breathable, but without a fabric swatch to feel and not having handled one in person I don't know.
Now this was a big story a few years ago. May want to google to see if my tale is correct. So from what I recall, in the U.K. a gentleman started a very high-end car cover company. And somehow he wound up murdered. I'm curious if this is the company (link following).

So a silk very thin form fitting or reveal cover may be the gentlest on the finish. You never want to drop a cover over the paint, always want to fold up the sides the rollup from back to front.
