S4 B8 Stage 1 or Stage 2 ?

OK. Deciding on which remap to go for. Will probably be either from MRC or Unicorn (if stage 1 - cheaper, but no rolling road test). But stage 1 or 2, that is the question.
I've seen the graphs and understand the differences on paper, but what do they feel like from the driving seat ?
Looked at plenty of threads from people that have gone from stock to stage 1 or stock to stage 2, but not found anyone that has tried stage 1 then gone to stage 2. Is going the extra worth it without upgrading other aspects of the car ? I'm not likely to track it as it's my daily drive.
