yours cooks by pressure and induction.
pressure feature is a big reason for the cost increase , and then some extra padding for the look.
all these machines work very very well .
I like rice , and aside for innate taste differences ( basmati vs short grain , etc )
I doubt i could taste the differences between properly used machines .
I do like the thicker ' pot ' in the induction versions .
which means Id like the thicker ' pot ' in the 5.5 size !
