If you currently have
Mavic 2 Pro, I would say it's still more than competent camera wise and skills of the user are more important.
Difference to
Mavic 3 simply isn't anything like jump to
Mavic 2 Pro from that tiny sensor DJI used in Mavic "1" and many other drones.
Though of course with same f-ratio in lens, bigger sensor collects more light and bigger pixels are also less affected by diffraction.
Though
M3's tele camera is kind of ace in the hole.
Its image quality isn't that great, software currently doesn't give RAW with it and also other controls are limited.
But it's still additional tool allowing getting some kind picture from smaller things/very different perspective than wide angle, or when getting drone closer would break VLOS.
Also tele lens gives something from those sunsets when wide angle view is "Where are the colours?" ordinary.
As for rest of the drone
Mavic 3 has definitely some very lovable features.
Like endurance/flight time giving more latitude in how fast/slowly you wear down batteries:
You can boost achievable cycle count of Lithium chemistry batteries lot by not always charging it to 100% and not discharging it to low charge.
Also coming from Mavic Pro (Platinum) power/wind resistance is awesome. Haven't yet gotten single high wind notification.
Though GNSS is still somewhat ornery.
Sometimes home point is locked fast, sometimes it takes many minutes.
But part of that variation is no doubt down to GPS jamming from Putinistan.
As for other aspects that DJI (dung)Fly should have been given major features/functionality upgrade before letting it anywhere near
Mavic 3.
You can't even check such basic thing as individual battery cell voltage without having to dive into menus.
And stock remote controller doesn't deserve name remote:
It's dumbmote with very little features for increased carrying bulk over previous Mavic controller.
Only good things are far easier to use/more versatile phone holder and great battery life.
Rest is downgrades to level of who ever decided to put it with
Mavic 3 deserving
R Lee Ermey in Full Metal Jacket style critique.
For the price and top compact status
Mavic 3's standard remote should have been like what
Mini 3 got.
Maybe DJI bundless it in future.
