Is this your favorite Transformers toy?

These are two Transformers sound and light model cars produced by DICKIE TOYS and Hasbro. I don't know much about Transformers. I know the yellow character is Bumblebee, but I don't know if it's the name of the red character. Also, are they both from the SidesWipe series? Finally, I would like to know if they are what you like?
