you mean the PU hot water pole hose is not good?
When you say 'good' do you mean as in, is it a good quality hose?
If so PU pole hose is very good quality hose.
Or do you mean 'good' as in is it well suited to its task?
The answer to this would be subjective based upon your exact system set-up, temperature of water used and personal preference - it would be difficult to answer this as the answer would vary for each user.
