Is Frank the better parent because he stayed or nah?

I personally feel like Frank sucked forsure but he never left and didn’t want to even give full guardianship to Fiona .. idk something about him just not wanting to give up his kids says a little something ..

Monica always came back and fucced shii up and left again, everytime she was around she would literally break their heart, they would be in tears. It’s just very inconsistent with Monica.. with Frank they knew what they were getting..

What you think?
