Forgive me, but ... thinking that because something is 2-4 years old it must be out of date is just sheer nonsense. I have a 40 year old Starrett micrometer which is still very good, and in use every day.
However, to the point. The Snow Peak GST-100 remains the Gold Standard in my book. They tried to discontinue it, but failed: consumer demand. I have 2 and use mine regularly.
Other good stoves are the later Snow Peak, the Vargo Jet Ti, the Montatauk Gnat, and some of the small Koveas.
Stoves to avoid ... ah well. Anything which creates a pointy flame, like the MSR Pocket Rocket, can be bad news for your pot and dinner. Anything with long thin supports (again, like the MSR PR), is to be avoided too.
