So women’s shampoo is just usually better?
gpt
Women's shampoo is shampoo. Better or worse is...well, it's just shampoo, mostly. Cheap shampoo or conditioner will *work*, technically. It cleans. But $1 stuff will make my hair feel permanently like I just went swimming in the ocean and it's miserable. I don't know whether *you* would notice any difference or not.

For someone with even shoulder-length hair, the 2 in 1 bottles you typically see advertised as "men's" are even worse. One cannot combine those two things and still have functional conditioner, apparently, so it's just noticeably harsher and unpleasant, and it's going to tangle more.

Buying them separately and buying good ones is more expensive and (slightly) more time-consuming, but there's definitely a difference. Most men just don't think about it because it's not really necessary when so many keep it short.
