I had two whisperlites, but I had problems eventually with both of them.  I used them for a long time, but went to something completely different, a snow peak giga power stove that uses butane canisters.  I actually still liked my Peak 1 Coleman--almost better than the whisperlite.  They all work and it really boils down to do you like to use white gas or canisters.  I thought the option of being able to use different gases would be a plus also, but in reality, I never used anything but white gas with the whisperlite.
