It seems that if I want to properly insulate our windows, I need to choose a full-frame window replacement vs an insert. Since our house has stucco siding, I fell this may quickly get more expensive than I anticipate.
Why is it more difficult to properly insulate a window if we replace with an insert instead of full frame?

It depends on how the inserts are installed, I have done a few insert jobs after sealing and installing trim pieces they worked quite well and were very cost effective. A full flange that is sealed is better but the cost on stucco can be many multiples the cost of an insert. If the inserts are fully sealed and trimmed out there is not a lot of difference. With stucco an insert is much easier than a flanged or full frame window.
