Personality wise I found them to be more difficult to look after, in my experience the males were much calmer than the females. Needs wise there's not much difference really

I've had male guineapigs all my life and as the latest ones I've had passed away:( I was maybe thinking about getting more as they are my favourite pet:) I was just thinking about female guinea pigs because it would be different as I've had males. But is there really any difference like there personalities or needs? would just like to know before getting more in the summer?:) thanks
