How does the experience of being Orthodox vs Ultra-Orthodox compare?

Similarities? Differences?

OJ and UOJ seem like reactions to emancipation, the Haskalah and the reformation of Judaism. Is there an even more strict version of Judaism, a Super-Ultra-Orthodox Judaism?

There's another movement whose name escapes me. It's not messianic Jews (who are Christians) but a kind of Judaism in Israel that puts heavy emphasis on the coming of the messiah. They usually wear knit kippoth and are at the leading edge of the settlement movement. Does anyone know what I mean? How does that movement compare to OJ and UOJ?
