Sizing wise, that would be accurate, add in a sod skirt. The wind performance is probably a fair amount better, although the SL3 does pretty well.
Two doors, easier for two people , and allows a lot of different set up options and more venting when needed. You will see when I post more photos in the next few days of some of the options two doors allows. It is far more flexible than an SL3. I know , a lot of people want a point product, but IMO, a product that can be pitched more open if need be, or pitched weather tight has a lot of advantages. Sometimes, real estate dictates pitch.
