I don't think either of them are easier to take out. Mainly since they are two seat wide. I would think they would both be kinda of a pain in the buttocks to take out. I have the All season ones, and they have been really nice so far, Sand vacums up really nicely. And to just use a clorox wipe (or i am sure there is something MUCH better to use, but its all i have right now) and it gets it nice and clean again.
so even though i have them i had to play favorites and say go with the all weather one's...but I think they are alot more lower mantainace (thats the main reason i got them in the first place)
