I definitely like Transformers more, for a variety of reasons, and see why they were more popular at the time and have stayed so, BUT it'd be pretty easy to do a list of 20 Gobots That Did Stuff We All Wish Hasbro Did With Transformers.
A lot of that list would be alt modes. There were some really cool and some really goofy, but nice and unique alt modes for the Gobots. They also made a bit more of the female characters, and did characters in different sizes long before Hasbro made Primes and Bumblebees to suit every price point.
