i find that a really good sleeve for any device is a better option than a dedicated bag. a sleeve can potentially fit more types of bags, which can adapt to any laptop, tablet or whatever your current needs might be. you can easily swap from techwear or tactical kitouts to a low profile backpack to a basic messenger bag.

whereas a dedicated bag is a very specific use case for a particular device. you might potentially be spending more because you need space for all your additional accesories.

i carry a separate eva foam zipper case just for the accessories (like stylus, cables, aftermarket multiport charger, gamer mouse, external ssd, card readers, dongles, other usb accessories) and possibly a separate case for my xbox elite controller. so that's already three things i would need stuffed into a backpack or other bag of some kind.

while a good sleeve was recommended in this subreddit before, it is somewhat loose because it was made for a tablet. it is great especially of its scratch protection the soft inner liner provides with padding. it is better than nothing. but i am still looking for one like it that fits better.
