What play speed do you use most often?

I used to do mostly normal speed with cheats so I can get the most out of my Sims' days. I don't have the patience to wait for them to pee or eat or sleep, lol. But the problem with cheating needs is that the default state is "Happy" and I hate that, so now I just try to keep their needs midway filled so they don't have that annoying buff. I've started using the other speeds just a little bit more because of this, but only when I want them to finish meals or showers, etc if it's taking too long. I did read that using other speeds can sometimes corrupt a save, so I minimize the use. I like to play households with two or more Sims, so there's usually something I can be doing while I wait for one to cater to their needs.
