I’d go with the Air 3s and keep the Mini 4 Pro.
As Jen said the Telephoto Lens is so damn useful and along with the obvious advantage of seeing a bigger drone further away it has helped me maintain VLOS while capturing some pretty good images for editing.
I’ve had the Air 3s since July and can honestly say it is better than my mini 4 Pro in every aspect bar one; portability.
I will keep my mini 4 Pro for taking abroad, or on long hikes, but will use the Air 3s pretty much exclusively come Jan 26.
On the subject of noise, I don’t find the Air3s noisier than the mini 4 Pro at all. The Air 3s has a lower pitch than the mini and TBH in my experience is largely ignored past 30m high. The Air 3s is so much more capable in high winds, and whereas the mini is fighting to maintain its pitch with it’s motors screaming, the Air 3s is quite happy. Random, I know, but it reminds me of a time when I was on an old 60ft narrow boat with a 3 cylinder diesel (I think) chuffing away happily on the river Ouse in full spate, and the little fibreglass boats (we called them tuppaware boats), were being tossed all over the place engines screaming like a banshee and getting nowhere fast!
I have no intentions of buying a mini 5 Pro anytime soon, but will no doubt get another mini drone when the Mini 4 Pro gives up the ghost or I lose it in an unfortunate incident (been close a few times but no cigar… so far).
