I can definitely see preferring TNG to DS9, if you can will yourself to ignore the first two seasons exist.
But how can you prefer Voyager to either of them? Voyager was explicitly designed to be TNG-lite.
Having all Treks to pick from and picking Voyager is like having all beers in the world to pick from and picking Budweiser.
Is the UK just generally anti-serialization? Most BBC series I've seen are very episodic.
I think that is the case sadly, those of us who like serialized arc heavy shows tend to be in a minority here in the uk in my opinion.
