Wow. I still have my GI mess tin in my extra gear box. Not quite right for my current style of hiking/outdoor adventures, but I may toss that in my trunk.

I have been going back and forth for a year or two on the Ti cup. i have a Brunton tea kettle and pack my White Box Stove in it. For a cup I carry REI insulated cup / french press with this you can press your coffee and drink from the same mug. Haven't had much reason to get the Ti Cup with this set up...but its a titanium cup.
