Well, I have both CabinMax and Osprey bags.
CabinMax are a great range of carry on bags of good quality, made to a weight and price, I would recommend them without hesitation for their purpose. I have two of theirs, one is like this one
https://cabinmax.com/en/home/218-tallinn-55x40x25cm-carry-on-backpack-great-for-easyjet.htmlwhich I use for travel for work, when I have a bike at the other end. It has the benefit of integral laptop pocket, handles on the side to carry along with usable backpack straps. Now I realise that there may be reasons for it, but you may want to question your wheels AND backpack vector. If it is carry on, do you really think you need wheels? lack of wheels makes the backpack-bit far more versatile and helps maximise the actual carry volume and weight.
The other CabinMax bag I have is a messenger style laptop bag, very strong and lightweight with useful pockets, but they don't appear to do that any more
Osprey bags are in a completely different league. Functional, designed by people who use them and as strong as they get. They also have a lifetime guarantee they stand behind: They will either repair the bag for a reasonable charge or replace free of charge. I've had two replacements on that scheme over the years. This gives you the confidence that your considerable investment is protected. FTR, I have a few Osprey backpacks for different purposes and use their "shuttle" range for luggage.
