Eminem isn't a text head, there's a difference, if you talkin textually.... then you pick whatever u must comfortable with, using a rhyme scheme and other things like metas.. (that can be for battling people, or just writing topically).... but after u do it for a while, YES, u do get used to it.. but switchin ya style is mainly a good thing, everybody dun wanna see the same ol same ol, basically..

Audio-wise, the beat is just as important as well as the rhymes.. some people switch up their styles according to the beat, while others stay mono-tone... u might have to practice, but it depends cuz for sum people it's natural once they hear a beat they can spit right away and stay on beat.. just depends really.
