As someone said, "It depends on climate". Where I am in Southern England is pretty unpredictable, we get Atlantic weather.
That means I will prune back in autumn, but not too far. Roses hate being at all loose at the base, this stops them having too much windage and swaying about when those Atlantic gales hit. On the other hand if we get on the wrong side of a weather system we get arctic air drawn down and it gets cold, that can cause die back on pruned stems. In Spring I re-prune, going all the way back to the bud I want to shoot from.
I saw someone earlier saying 'Better to err on the side of caution', not my opinion, leaving too much leads to weak growth and less bloom. I leave three good buds on my final prune on the whole.
I quite enjoy shaping a bush, taking out cross branches and such, but there is a film of two identical rose beds. One gets pruned by two experts who take all day over it and the other is chopped square with a chain saw. Months later in full flower they look the same. I don't know what would happen in following years, taking out all the rubbish and letting the air through certainly seems to help contain fungal infections.
