Girl or boy easier?

Hi mummies! Just something I’ve been feeling for awhile and just wanted some thoughts - is it true girl is easier than boy? My LO has been a terrible sleeper since young like mega short naps since birth and woke up nightly till 7 months and now after started again. And then my sis in law has a daughter and super easy to sleep anywhere, can go out all the time (whilst i look like death the first 7 months). Then mu mum in law also keep asking me to pray i give birth to a girl next time etc… keep saying girl is easier boy is hard. I feel scared and the pressure of having a girl if I have a 2nd kid and it’s not a great feeling.
