I've done MATH3061 and personally I found it interesting, but I agree with Carrot that the course is a bit watered down for the topology section. Depends if that's what you are after though. Paunescu (the geometry lecturer) is not that great, but if you go through the tutorial questions you should be fine.
I didn't do MATH3068 because I did MATH2962, but analysis would certainly be a good subject to take. I found it pretty interesting and relevant, plus I'd imagine the normal stream is a bit easier than MATH2962.
