it depends on your preference. they made both boots, one for lower price, and also because some people like different features. saying one is a better boot really depends on the person and what they want out of the boots.
i would suggest you go to a shop and try them on. spend time on boots, they matter the most. try both on, different sizes n such, and get some adjustments done by a boot fitter if needed (go to a store that has one in the first place, dont waste your time at a general sports store where no one knows whats going on and you're given a boot 4 sizes too big so you can grow into them, ask them if they're a qualified boot fitter). it may be a little more expensive, but you'l be talking to someone that knows how to properly adjust/fit boots and what kind of boot you will be looking for with your foot. you can decide from there. if you buy the boot from the store with the bootfitter, most will fit/adjust it for free, for aslong as it takes to get the right fit. also, they should ask, but let them know where and what terrain you're skiing, and be open to other suggestions they may have about other similar companies/models. these suggestions will come based on the characteristics of your feet and how you ski.
