Wich one is best for editing and gaming use
Hi bro, Macbook Air is good enough to handle video editing tasks even with 4K footage. the question comes whether you need the extra features you see in macbook pro and your budget allows or not.
Macbook Pro has 120Hz ProMotion display, better look and design, additional fans to cool down during video rendering works. So if for long term usage you need such upgrades go with macbook pro.
Otherwise Macbook Air is sufficient. exprience both at apple showroom once and make the decision bro. that will help.
Consider applecare+ when you buy with discounts and card offers. for 3 years you can protect your mac completely.
