The booty I'm using this season is the Race Power Over Shoe. In a word...in two words: they freakin' work. What else can I say? They keep my feet warm and dry. I guess I could trash talk the Pearl Izumi Amphib booties I've been using for years — er — I mean, compare and contrast. What it comes down to with the Amphibs is basically that the zippers suck. They are hard to zip when your hands are warm. In fact, you're lucky if you don't blow out the zipper putting them on. Then there's the issue of taking them off with cold hands. Operose is a word I would use...if I knew the meaning of it. When I'm in the dressing room at the shop, trying to take them off after a cold ride I let out such streams of profanity that my co-workers have to tell appalled mothers, as they cover their child's ears: "sorry mam, that's Tommy, he has Tourettes Syndrome, we get a big tax break for employing him...please don't sue us."
Conversely, the Gore booties utilize a velcro system. I can put them and on and take them off standing on one foot like a damn flamingo. The version I have are uninsulated, for colder weather riding (sub-20°) I'd probably recommend the insulated version. Or you could just do what I do and cut a hole in the bottom of an old wool sock and pull it over your shoe before donning your booties.
