It might be great for a 5 year old, but you might struggle. Quality-wise (animation, story, acting and dubbing) it's doesn't hold up to G1. But there's three kids as main characters (as well as their two bullies) who get to hang out with the Autobots, and some kid-friendly Transformers they "own" (skateboard, bike, push-scooter). And a common joke about the fights is that they mostly involve people holding each other fists and trying to push the other one over, so it's maybe not as violent as some other cartoons. There is some death towards the end of the series though. It's also worth noting that it's very much an ongoing story, rather than G1's mostly standalone episodes.
