Prima vs Boss

I've played in the prima network since I started playing poker in July this year.
I just startet clearing a bonus at a boo site and man is it soft. People play EVERYTHING. 72o? No problem! Even after a raise people limp in with 72o. And they go to the river...

My question, is prima considered tight? I always hear party is soft, is it equal to boss? or even more soft (impossible)
