I use them to set up a home for a sim if it's "in character" for them to be rich off the bat. I'll use the build cheats on lots we can't normally build on if I'm feeling the need to redo a lot. I'll also use cheats to makeover sims now and then.
I don't really consider it "cheating" either. It did use to be a self challenge for me to not use it but there are many ways to play and sometimes I try them out.
I mostly would rather not cheat mostly because I like for these things to be in game options and I don't want to look up how to do it all of the time.
