I don't hike in sandals (with my clumsy foot drag, my feet would be shredded in minutes), however I walk all over the city in my Chacos and I love them. I have to admit, the first month I had them, they were a bit of a pain and I had to get used to walking different. But, because I have trouble with my arches I figured they were the best way to still be able to wear sandals all day and not have plantar fascia pain.
Now I love them and am missing them horribly since the dog at the straps. Luckily, Chaco will re-strap the soles relatively cheaply. Just have to remember to bring them to the office one day so I can ship 'em off.
I never had good luck with the Tevas - and I tried a few different pair. My husband prefers them, but he has massive foot stink problems with both the Tevas and the Merrels. I think it all depends on your foot, your gait and your individual needs. Lets face it, if there was one shoe that fit everyone, lots of folks would be goin' out of bidness!
