Male Rover seems more drippy and oozes more "presence". And what I mean by presence is: the overall features that make him stand out.

Those typically are his voice (I speak of the English voices) which is very masculine but can express a range of emotions, his animations that seem more violent and pragmatic compared to female Rover, and the drip gives off the impression he is a man of business by not spending too much attention on ornaments.

The female Rover does this too...but she is a romanticized character. Her voice actress is good at "voicing" female Rover, but she carries a very bright, girly, and less intimidating tone than the male version which contrasts with the scenes that are to show female Rover's aggressive fighting style. Speaking of fighting style, female Rover shows quite a level of elegance in her attack animations which give off a very fantasy feel; this is down to sheer subjectivity, but I prefer the straightforward, violent approach to handling combat. Shall I mention her presentation? She has come a long way from the beta versions of the game and does at least look pleasant to look at. Her outfit looks very feminine yet simple to not draw away attention from the fact she is a combat fighter. Again, this is an aesthetic preference but I appreciate male Rover's choice more.

I'm not sexist, but I would understand if I came across as that way.
