I think a lot is down to the individual personality rather than breed.
I have currently two teddy sisters, and they couldn't be more different in temperament!
If I were you, I'd ring around a bit and then go to the rescue within reasonable reach with the most "free" guinea pigs and handle them. You'll know when you've got the ones for you!
And more often than not, it won't be the prettiest or the ones you had set your heart on from a picture; as pictures don't convey the personality as much as handling creates a connection.
My Dizzy chose us (not the other way round!) that way, and later on she decided on Llewelyn as her new mate; both guinea pigs had not been what I had been looking for, but have given me and each other so much joy!
