I'm another multiple decade user of the Whisperlight, may not be the be all end all but they have never failed me (have one multifuel and one white gas).
I would also agree with the Seva 123 if you can get your hands on one. I had one of these but in a fit of youthful stupidity sold it. I did keep my Optimus 8R which shares the guts of the 123. It's a great pice but a little large for Moto camping.
The thing about the MSR that I like is that it fits in my cook pot so it doesn't take up any more space than just the pot.
