If my daughter was full time student in 2018, we paid her college, then graduated in May and was married in June, moved away in July, should we claim her as a dependent?

With new tax laws, i wasn't sure it would reduce our tax liability to claim her as a dependent and based on our income level if we can get tuition credit. adjusted gross over 150K.  

Also-would it benefit her more to not be claimed as a dependent, as she and her husband wanted to file as married filing jointly.

THANKS for some help
