I don’t think there’s very many actual “brands” designing and innovating on unique models for these, I believe it’s all just renamed Chinese white label from the same or similar factories.
Best you can do is get one that fits all the boxes you’re looking for, make sure it has a strong brushless motor, good reviews and that’s probably as far as you can get “BIFL” out of these.
You might want to consider just saving some money and getting one used.
