Issue with potting soil, you have to cap it. Its messy. Its hard to move plants. Specially heavy root feeding plants. So its best to plant them and then dont move them at all.
Benefit with potting soil, its cheap. It is a great choice if you want to use Walstad Method. I have been using it over a year and couldnt be happier.
Although I do not have any direct experience with fluval stratum but I hear that its great. You can move around your plants all you want. But its pretty expensive. Specially, comparing with potting soil.
