Always used only branded flashes. There are two SB-910s available. There was a need to install a group of flashes (4-6 pieces) in the banquet hall. It's a pity to put expensive original ones. They can drop. After reading reviews on the Internet, I found Godox TT600 - almost eight times cheaper than my Nikon SB-910. Bought three pieces to try, I liked them. I will take more. I set it on fire with Godox XPro. Recharges quickly with good batteries. Flash data without TTL, they are not needed here. And an AA battery option. There are also TTL and / or Li-Ion batteries - more expensive.
