Hi! The wear is both the scuffed corners and also sagging. The sagging is also the nature of the bag.
Keep in mind I use my bags daily and do not baby them. Sure, I could baby them, but I do not see the point of stressing over a bag or any other item. Bags are meant to be used, not to sit around in a closet.
Also, in a twisted way, I like the look of my bag a bit beat up. It's the sign of a well-loved bag and not one that has been babied or only used for "nice" events.
That said everyone is different and you will have to decide what works for you.
I took photos of my green CCH. You can see the scuffs on the corner, you can see the sag. You can also see that while it has feet, the corners hang "past" the feet, so the feet is really useless to protect the corners hence the scuffing problem. It's really the way they folded the corners of the bag instead of making it more a true seam. The Hermes Kelly bag has true seams and is not a "folded corner" like the CCH.
On color... if you are only going to buy two Chanel bags, I would think about the full seasons. Black is great for fall/winter, but not so great for spring/summer. Yes, one can say black can be worn with everything, but personally, I find it a bit odd looking to wear a black bag with light summer clothing. You are thinking of either dark red or beige, so think how you can wear these bags in all seasons, not just with a few outfits you have now, especially as it is approaching fall and of course this collection is the fall collection.
I am excited for you to get your new bags! All I can say is don't rush on choice of color. Don't just pick from what is available now and settled if it's not a perfect color. If you are hesitating a bit, wait... CCHs come back every other season with new colors.
For me, I am waiting... I already have two red Chanel bags and a beige claire (none of these bags that I wear often due to the color).
