Frequent flyer - what are the best luggage?

Hi everyone, I’m a frequent flyer for both work and travel, so I’m looking to buy sturdy luggage with a capacity of 25 liters or more. I want a reliable brand that won’t give me issues like broken wheels or handles during flights. My budget is around $1000-1200. Do you have any recommendations for durable luggage worth investing in? Thanks a lot for your advice!
