I personally hate'em. More ludicrous symptoms of the "Batman is unbeatable" and "sell more toys" manias.
They're not what Batman's about. He's a human man who has awesome vehicles, but not Iron Man shit. It's just a totally different milieu.
The only armored Batman I liked was Miller's DKR#4 outfit. It was ramshackle and was only powerful because he could hook it up to the city's power grid.
They juiced up that armor in the animated treatment of DKR and BVS; didn't care for that.
I agree. Fine for an Elseworld or AU rendition of the character but not for the main line.
