The Soft-Lite Imperial LS window is one of the better vinyl window options out there, probably in the top 10 vinyl windows on the market. Soft-Lite spent quite a bit of money in the research and development on their top two windows and it shows with this model. Not their top of the line window, see the Soft-Lite Elements review, but their small step down down. Depending on the price point and quality of installation, this model should be considered a good long term value purchase.
Standard features include a Integral lift rail, Comfort foam frame fills, triple weatherstripping, a true sloped sill, a recessed sash lock, a super spacer and locking exterior fiberglass mesh screen. The Imperial LS also offers several very nice upgrades from the Soft-Lite Pro window, including a Kevlar reinforced fiberglass meeting rail, a more precision corner weld system, and a coil balance system. The Imperial LS can be ordered in a number of different glass options, including the low-e, Ultra and Ultimate glass packages.
Consumers can choose from two interior frame colors (white and beige) and five interior wood grain laminates (maple, brazilian cherry, cherry, medium oak, and light oak). The window also comes in 15 exterior colors, including some rather bold color choices such as Royal Brown, Forest Green and Bronze. The Imperial LS model can be ordered as a casement, double hung, picture, slider, or awning - the same options available for the Elements Series.

Andy, I agree that on paper these two windows look pretty close, it's one of the reasons that choosing the right window presents such a tricky prospect. However, the Soft-Lite Imperial LS window is by far the better made of these two windows. Assuming the installation is equal in quality, I wouldn't hesitate to go with the Soft-Lite option.
