I will stick with a univalve, those taps are awful to use imo.
Can you adjust the flow infinitely with a univalve?
No need.
Imagine this scenario...
You are cleaning a front door in sub zero temperatures. You want to rinse the glass, but gently so not too much water flows. I turn the tap to just above a dribble and scrub.
Then I turn it up a little more ... the exact amount depending upon the size of the glass panel(s).
Very little water on the step, if any.
Job jobbed quickly and perfectly.
Rarely a need to trad. Rarely a need to 'buff' with microfibre. Rarely a need to sweep and/or salt.
And of course, the icing on the cake ...
No flow controller.
