Cover that leaks the least?

Which cover is known to be the one that leaks the least? I'm thinking about getting the one Toyota offers (PT954-34223.) Are there better ones than that? I think I'd like that tri-fold.

Thanks, but those are a little out of my price range. I'm not wanting to go over $1,200.

 

I have the MR pro from SyneticUSA. I think I paid $900 for it about a year ago. I specifically wanted a canister cover, I realize they aren't for everyone. I installed it myself and its water resistance is much better than I had anticipated. If I go through a carwash or wash it myself and spray directly at the rear two corners I will get drops that enter. I haven't noticed this happening from just rain. Its never enough to worry about. Literally just drops. May be worth checking out there website or ordering from Amazon (which I did because they had free return shipping if I wanted to send it back).

 

My <$200 Gator tri-fold has held up surprisingly well for the last 6 years and the only time I get any water is at highway speeds. I'm not completely convinced it isn't coming from around the tailgate. Very minimal intrusion to say the least, and it's only at 65+ mph.
