Wear and tear of leather is generally related to how supple the actual leather is. If the leather is clean and well moisturized it will stretch and move under you more naturally, resist (and even self heal) minor abrasions, and will look less worn over time. That said, most modern cars use coated leather, which has a semi permeable membrane designed to mimic the qualities of uncoated leather, but also works to protect the dyed leather beneath it. While coated leather does offer increased protection, it is still prone to the same attacks from dirt, abrasion, UV, staining and everything else that uncoated leather would be prone to.
My regimen is simple. Every time I wash my car, I use one of the moist (to wet) microfiber towels that I used to dry with on the seats. I wipe each seat down completely, allowing the moisture to dwell while I wipe the remaining seats down. I then come back with a dry microfiber towel and 303 Aerospace Protectant. I firmly wipe any remaining moisture off of the seats and spray a single spray of protectant onto the towel to wipe down each seat. I've continued to use this technique for coated leather seats in other vehicles and I always get compliments on how the seats appear to look brand new well after purchase.
No real world comments on ceramic coating leather, but to me it seems gimicky and possibly even detrimental to the long term wear. I'm all for exterior ceramic coatings, so I'm not a detractor of the technology, but putting a coating over something that already has a coating that has been specifically engineered for protecting the leather seems redundant. I dunno... maybe need to read up on it more.
