I love Sea to Summit stuff. I have their collapsible cup and bowl, though mine are several years old and thus don't have that grippy finish that cup has. They next inside each other and take up a tiny fraction of the space my rigid cup and bowl used to. (The StS mattress I have is also the favorite one I have ever owned.)
As for the rest of the kitchen, I do a lot more than boil water, so by cooking gear is probably more extensive than most. Always induces either my MSR Dragonfly or Optimus Nova liquid fuel stove. The former is for longer trips because it has a larger fuel bottle. I also bring two pots that nest inside each other. All in all, I think the collection is efficient for what it can accomplish.
I do more than boil water too, I found that I don't need a second pot though. Anything I make that I need to boil goes into the stainless cup, for all other cooking stuff, I use the pan. But I travel alone, if I was with another person that would probably have to change.
I'm trying to cut down on weight, but in doing so I have to weigh in the costs such as is it worth it to pay $50 or more for something and save an ounce or two? Then you run into the lighter-weight stuff not being as durable. So it's a battle trying to find the right combination that will give you durability vs weight vs cost.
The mess kit I have is cheap, but I had a lighter-weight aluminum kit but it only lasted one season. The one thing I have noticed is that eventually you'll burn food, and sometimes that burnt stuff won't come off like it did with the aluminum mess kit, so I threw it away because it was cheap, the same thing I can do with this Ozark Trail kit, if it gets messed up I'll just throw it away and buy another one at Walmart, but the stainless steel kit I can scrape away hard on it to get burnt stuff off without damaging it, but someday I might not be able to do that, so I'll only be out $10. But if you burn crap on a Ti pot, or especially in a non-stick pot that pot is gone. I would think the Ti without a non-stick coating pot should hold up as well as Stainless, but I've never owned a TI mess kit so can't answer that, but it seems that would be the case. I'm not a good cook, so burning stuff is something that happens when I cook! LOL!!
A lot of backpackers and bike campers don't even take a mess kit or a stove to save on weight, they eat packaged stuff that requires no cooking. I like cooked food better than pre-packaged bars, or bags of trail mix. I do take some pre-cooked foil-packaged meats, but I will heat those up to make stuff, but I don't have to heat those meats. I also like coffee in the morning, so that means I have to be able to boil water at the very least. Everyone has a different take on what they want to eat out in the field, you just have to find what you like best.
YouTube has all sorts of videos about how to eat when backpacking, which applies to bike camping too, and there are a lot of sites that show you how to do it cheaply without buying those expensive camping meals in a bag that start at $8 and go as high as $18, geez for that kind of money I think I would just find a restaurant! Going to a restaurant would also cut down on food weight, but the cost to go camping would skyrocket, but some people are ok with that.
