I wouldn't make too many assumptions about the 110 based on the men's 120 . The 120 is a softer version of the men's 130, but it's also more than that. It's also positioned as a budget boot, where Lange went with a much cheaper plastic (PU) that's much heavier, so Lange had to manage weight and performance in a way that they don't with the Grilamid 110 and 130. It also uses a less performance-oriented liner than the 110, and the 110 is a step under the 130. The men's 130 uses monoinjection plastics, which allows for the most consistent, smooth flex, but at the cost of being able to get in and out of them as easily. The 120 and 110 both use dual injection molding with a softer plastic in certain zones for easier on-and-off. The men's 130 skis like an inbound boot, but the 120 doesn't have quite the same reputation, and getting into the construction, it's easy to see why.
The women's 110 is a little more like the 130 in construction. But there's not really an authority source that compares boots across brands. We don't have our own version of Jonathan Ellsworth at Blister who fits happily in just about any LV boot on the market and has owned and skied all of them with detailed notes. And even if we did, men have 7 boot flexes across the entire market with brands using almost identical flex runs and consistent prices (ie. 120 boots are almost always cheaper than any other 130 boot on the wall). Women have 13 flexes. Brands have 0 consistency in the flexes chosen (like one like will go 90, 100, 110, 120, and a competing one will only include 90 and 120). Flex and pricing aren't as clear between brands.
I checked a few review that indicate the XT's a twinge softer than the RX110. Likewise for the XT3 110 feeling stiffer than the flex indicated. Based on the construction, my gut tells me it's likely closer to a "true" 110. With the Grilamid shell, there's not the same weight incentive to soften the boot.
