Fibre Broadband Sign Up

Anyone any experiences with signing up for Fibre broadband in rural carlow. Had an operator call here looking for me to sign up. The usual sales patter of x y and z on the road having already signed up. So what I want to know is, is there any real difference in any of them? They will all be using the same infastructure. This crowd were offering free installation in terms of ducting/overhead cabling. Anyone any experiences with this yet?
