Hendrik Morkel waxes philosophic on a most practical matter:
… I’m convinced that it is on average lighter to go with an UL stove and dehydrated food, as I reckon it will be tastier and give more (mental) energy. …
Hiking in Finland – Food for Thought: Stoveless backpacking
I like that conclusion. I normally have 2-3 hot coffees in the morning, a cold lunch — and a big hot meal after dark.
My stove of preference is still the MSR Reactor.
Should I go to something lighter? 🙂

The main goal is to be happy, so people should do whatever they like!
But if the goal is to be efficient, then there is no question the alcohol burning cat can stove ($0) is the way to go. Water comes to a boil just as the fuel runs out, and dry food is added (no simmer).
Personally I can’t be without hot food on a long hike. I love my little msr pocket rocket. Weighs next to nothing and the rain doesn’t seem so bad if you’ve a cup of tea in hand!
Just now beginning to experiment with DIY beer can alcohol stove. MSR pocket rocket is my dependable backup for now.
