TemplateStacks or SubStacks, Which is better?

[Cal Horner]

There comes a time in the use of LiveCode when you run across the concept of
a template stack or a substack as a entry/data display form. The questions
that you might be faced with are:

 Which one should you use?
Which is the most efficient as a form(date entry) etc.?
How much memory does each type take up?
What are the difference in speed?

I'm sure I could go on and on and probably you could too.

I'm looking for some direction on these and other questions like these and I
would expect that the answers are hidden somewhere in this forum.

If you can "shed any light" on these perplexing questions please take the
time to respond.
