More important to who and why? I would never try to classify either DH's or my job as more important.
I work 3 days DH 5, I earn twice as much as DH in my pt role. However we have chosen that DH has this particular job as it is near home and means he can look after DD one day a week and do daycare pick up on the other 2. He could easily earn more, but would be away some nights a week and wouldn't be able to look after DD. In his line of work it is very important that he remains current in his work, therefore he can't really go part time or stop work.
Both our jobs are important for us and our family and neither of us is willing to give up our careers, so we have both comprised (he for a lesser role, me by going part time).
We are both doing what we can, but it isn't a competition as who is more important.
