From a playing point of view I always liked Sarsfields, Naas (old and new), Clane, Caragh, Confey, Athy.
As a supported its easier to name the ones I never liked! Kill, Suncroft, Nurney, Robertsown, Kevins, Rathcoffey, TMH and Hawkfield should be a lot better for supporters.
Loved playing in county grounds but dressing rooms are awful and as a supporter i normally have to piss in an empty bottle if staying for 2nd game! (bloody county board!!! Sorry couldn't resist)
