ᐅ Which wood preservative finish to choose

Hi,
quick question: Which wood preservative stain would you recommend? So far, I have always used Xyladecor. However, I have recently read quite a few negative reviews about this product.
At the moment, I am not tied to any manufacturer. I already know which product the previous owner used to stain the terrace and other areas.

We use Saicos wood protective glaze and Saicos wood and garden paint. It provides good coverage, is easy to apply, durable, looks nice, and you can simply paint over it again directly (after cleaning thoroughly, of course).
