Far better to freeze embryo's if possible. Plus it's bloody expensive too with no Medicare rebate unless it's for a medical reason (for eg starting cancer treatment). What I wish is that all these experts that are so blase with their advice such as "oh just freeze your eggs" or "get the embryo's PGD tested prior to transfer" would be completely honest and transparent regarding costs of doing these things, success rates and the criteria that has to be met to achieve these things also as I believe it gives a false perception that it's achievable/affordable for everyone when it clearly isn't.
Same with the amount of Cycles needed. I reckon just cut to the chase and tell the truth about how many embryo's you'd likely need transferred depending on your age to get a take home baby. That's where the reality lies IMO.
