iPad Air (A14 Bionic) vs iPad Air M3

I have an iPad air 4th gen (A14 Bionic) which I purchased all the way back in 2021.

Recently with the new launch I have been considering to upgrade to the new iPad Air M3.

Is the worth the upgrade or should I stick to my current one and wait with the hopes of better hardware upgrades on the next one?

What are the pros and cons?

Cause on Apple’s comparison website it didn’t seem pretty convincing enough apart from a chip upgrade like am I missing something?

Also I’m a huge sucker for the space grey colour and fear that next year they might phase it out like every other product.
