Here's my take on it all.
If I was making my choice now, I would still go with the
Mavic 3 and here in Canada there is no option to get the refurbished
Mavic 3 from DJI or an approved reseller. Why? Because it provides options and creative potential everytime I am up in the air. To me the price differential is worth it. I often don't think people understand importance of having TWO cameras on one drone. I find the 7X optical Tele lens very useful and even though I don't often use images from the digital zoom, I find it very useful for exploring.
In a way the same sort of complaints have happened with the
Mini 3 Pro vertical shooting mode - many people have complained about its usefulness but here again it provides options and creative potential that didn't exist before.
With regard to the
Smart controller, I am not sure if the OP is referring to the new DJI RC with built in screen or the RC Pro. Here again there are options. I have the RC Pro and although it is expensive, I love mine. It is fast, bright and has the ability to load additional apps which the lower end DJI RC doesn't have. In addition many people who have the lower end RC seem to have to buy a screen shade to help with seeing the screen in bright conditions.
Regardless, good luck with your decision whatever it may be.
