Vladimir, interesting to see Polish seeds.
Betalux is an improved version of Beta. I will have Beta this year. Betalux needs extra magnesium fertilising. It tastes better and you don't see the magnesium deficiency on the leaves.
Poranek (Morning) is very tasty and a good producer.. I think that Poranek prefers cooler climate. When the summer is very hot you pick last fruits before the end of August.
