Unless you have an example of how you personally will exceed the graphical capability of Unity then their comment is strictly based on holding a bias towards UE4. Even if UE4 surpasses Unity when graphics are pushed to the limit in terms of realism and lighting that doesn't mean you should throw out Unity. Will you be pushing the graphical capability of Unity with your project? Do you have an artist on board who is going to put your game graphically on par with AAA games that push the envelope? If not then it doesn't matter.

If you know C# I would suggest trying Unity, otherwise try both engines and see what you like. Learning C++ is an option, and so is learning Blueprints if you want. Programmers should be open to taking on a variety of languages either way as they're additional tools that we can use when the need arises. Just don't discount the benefit in working in a language you enjoy and one that is familiar.

I've used both engines for games and they come with pros and cons, but consider that some people will talk great about the engine they like and use, and bad about the one they don't. Such comments like “UE4 has better graphics so don't use Unity” are examples of such comments. Even if true, this only matters for people looking to push their game to the max and get the best visuals possible.

@Rutin Thanks for replying, I wanted my game to have a similar art style to super mario Odys where there are really nice bright and vivid colors, but I heard Unity has difficulty with working around lighting and shading unless you have a whole team that can handle just that aspect. Which is why I hesistate on pulling the trigger on it . Its just me for now making a prototype I was planning to pitch to some contractors

I would suggest going beyond what people tell you and actually do some research. If you have an artist on board who knows how to do stylized pieces, and you have someone who can write shaders then you can output a variety of results in either Unity or Unreal. Maybe I'm wrong but Mario Odyssey just looks like the textures are stylized and they use PBR which Unity or Unreal can do. See the link below…

I found some references of Mario Odyssey in Unity:

Your lack of experience in either engine will not serve as a good foundation to come to any real conclusions regarding the limitations of either engine. I would suggest you just pick the one you're already leaning towards which seems to be UE4.

You can essentially make any game in UE4 just like Unity. UE4 has a reputation of being geared towards FPS and TPS games, but any competent programmer can develop a variety of games in UE4.

All you have to do is search around:

its not as great as odyssy

Well you have to put forth the work and make it look as good. Get an artist on board… Create a shader (if what UE4 has doesn't meet your requirements) and environment that does what you need. Comparing the “look” of Odyssy which is made by professionals to something an indie made and put on YouTube is not comparable.

Although I don't have direct experience in this matter, I've heard that Unity has trouble with loading large spaces (hence Mechwarrior 5's long load times). For Mario Odyssey With Guns, large spaces would be an issue worth investigating.
