Lequel est un meilleur texte en termes de performances ou une fonction TextWidget extraite
TextWidget function is more useful than multiple texts.
It's absolutely a good practice and if any changes need you can able to change centrally and it's time-saving with clean code.
You do not get the execution speed issue. And more important things, in both widget and function you just call a single Text widget.
That's why there is no performance issue. You go for the second one for good practice.
