I can tell you that I've experienced worse with Lovestruck at launch, than I did with For Rent. Sometimes I don't notice the same bugs as other simmers but my game was playable. This time I experience some lot corruption with Lovestruck. I had to revert to backup after updating for Lovestruck. Just keep them saves backup somewhere on your desktop, cloud, or USB. I think the For Rent feature is worth having because you can build apartments in different worlds. It's a feature that expands gameplay. That means you can have more space to build other stuff too.
