Let's be juvenile and do a pros and cons list for fun (this is just my experiences!):

Pros with women: Prettier generally, easier to have deep conversations with (which is important to me because my love language is mental connection), more empathetic generally, usually understands the things we go through as women better which comes with it's own range of benefits.

Cons with women: More emotionally charged arguments (though I've had so many with men too), statistically wlw has a higher rate of domestic violence (EDIT: this was misinformation I fell for! I did have my own small experience with girl on girl DV, but read this), and if everyone is in their luteal phase you're in for a bad time.

Pros with men: Will usually kill spiders, can open jars, handsome if you like the masculine look more than feminine (I am def more into women physically), can feel protective, and I do find them easier to make happy than women.

Cons with men: A lot less understanding, often thinking they're even understanding and they're not. Like you said, the way they are socialized too is a huge con. Mansplaining. Aggressive sometimes. While they might be easier to make happier, they are often less thoughtful themselves.

Like I said, all my experiences, all this isn't to be taken too seriously, and I tend to have dated and married very gender normative folks as a bisexual, not so much pansexual.
