They are both a big improvement compared to old ways.A two stage will usually run for a certain time say 10 min. then if it didn't reach temp. it kick's up to high heat. A variable will keep track of how long it ran to reach temp. the last time it ran and adjust output to run what it's deems appropriate.Although it might be more precise than a two stage I would not spend a lot more to get a variable cause it might not run that much different than the two stage.
