Sorry to say, if you got the standard stainless steel you're going to regret it because of all the cases it scratches the easiest . You'll have scratches within days. Titanium being the next worst.
Now, stainless steel space black on the other hand, is magnificent. It has a diamond coating and therefore does not scratch. You will see finger prints but they just wipe off.
Both the regular titanium and space black titanium scratch quite easily.
Any aluminium color and stainless steel space black are the best bang for the buck. Ceramic is extremely high quality and will never scratch. Quite expensive though. Titanium because of the price, I would say is overpriced. Apple is known to use titanium in the past so that's why they're using it now again as a materials alternative. They're not using it because it provides better watch build quality.
Sorry to say but in my experience I cannot agree with you. I have had 2 ‘regular’ SS AWs and neither of them have gotten any scratches on the case you could see if you are any further away than about 3 inches. I have had my S4 since release day over a year ago and only removed it over a stretch of time while I was doing some house painting this past summer. I try not to subject it to any abuse but inevitably I bang it into things on an almost daily basis, and it is essentially pristine. I did a move this year where I was smashing it often while moving boxes and items around, I wear it at the gym on a daily basis and never give any thought to having it on until my carelessness results in contact with something. Not a single mark on the screen and nothing on the case. I’m wearing reading glasses right now and on the closest observation I can make I cannot see one scratch anywhere.
My SS is next to bulletproof, IMO. S
