I have no experience with the MSR Duralite line, but I do use the Snow Peak Titanium 1400, 900 and 700. If you get the Titanium Trek Combo as a set, you get both the 1400 and 900 for about a dollar cheaper than buying separately. I use the 1400 in winter melting snow, the 900 for two of us and the 700 when alone. When stored, they all nestle within each other for a nice compact unit.
I re-hydrate food as well, but I use a quart freezer bag in a cozy, so I only have to boil water in the pots. No clean up (besides licking the spoon) is needed. Once you get past eating out of a ziplock bag, it is much easier, less hassle, and much faster; unless of course you like cleaning up dishes!
