I started off using unger.
In all fairness though for traditional work it's all down to which cleaning fluid you use on windows.
Although I have a tendency to chop and change, which brand I use at the moment.
No one brand is the best.
Kind regards.
Have you tried GG4 Mr Bungalow?
I only use GG4 with a capfull of Sorbo Glide in the bucket, when I use Trad.
