Kind of a tricky one to answer for me. The wife had only her mother (the rest of her family never were around or cared) and I got along just fine with her, she passed away about 5 years ago though.
With my family, I get along great with my dad but tolerate my mom. Dad has always been a great friend along with being a good parent. Mom on the other hand has only been a parent that refuses to let me lead my own life or make my own choices.
So I guess it averages out to 50/50.
