IIFYM vs ScoobysWorkshop

I used IIFYM to calculate my recommended calorie intake, and it feels like a lot (to eat, I mean). Admittedly I've not started religiously tracking/weighing everything yet but I only exceeded it yesterday with a trip to McDonalds and I wasn't an angel for the rest of the day either; still in holiday snacking mode. Scoobysworkshop is giving me very different results, and now I'm not sure which to go with.

Originally I figured I'd stick with the original IIFYM numbers for January to see what happened, now I'm wondering whether I treat the two numbers like a range, or maybe if 1900 calories is too many, I see what 1550 feels like and if I'm satisified, I go with that. Can I have some thoughts?

My workouts are not intensive at this point so I haven't factored them in
