My bb is 6 months old now. Should I feed him with porridge or rice cereal? Thank you!

I start my lo [6 month old] with Friso Gold Milk Cereal because you no have to add in anymore milk just add in water. Which i feel is very convenient especially in the morning when you're in the rush. during the noon I vegetable puree which i try to give different kind to try. each vegetable puree i let him try for 3 days I only start giving porridge around month 10. However till now his breakfast is still Friso Gold Milk Cereal but with apple puree
