Least it's more consistent on that front like Shonen, also that's basically the Super Robot genre in a nutshell. And how can you not like the Brave Perspective which began with it?
Heck it's responsible for a majority of the tropes found in much of general anime.
Oh it is just my personal taste. I do very much like the Gundam series but I do not go nuts over them. I simply just like em. I think they are cool.
But like I said, I am looking for mechas and mechas are machines. They should have mechanical feel to them. They are robots. You can only do so much with it before it starts to feel like something else.
That's what I am never really on board with them because most would go beyond those expectations and take you out of your immersion and you would find yourself all of a sudden watching Fantasy instead of SciFi.
Think of it this way: what if you watch a WWII documentary and then all of a sudden you completely find yourself watching the show but they are using a rapier, katana, crossboss and etc.
Or they are using magic and superpowers like the Marvel and DC superheroes on a WWII documentary?
It kinda ruins it, no? It is interesting and exciting. It is very likeable but does it fit the "WWII" expectations? No.
Now, say that it's WWII, the show goes in all about experimental weaponries and futuristic human evolutions. They can get away with showing missiles, lazer tech, jet propulsions (rockets). All these techs that are not existing yet in that timeframe.
That would be Sci-Fi but not Fantasy.
Or how about the forced evolution experimentations that were conducted. They could talk about how there was a push on developing the master race, etc. People with telekinesis or telepathy. All were experiments that were conducted then.
They are still within the realms of WWII.
Gundams that are meant to be mechas and all of a sudden having some sort of superpowers that is in line with Marvel or DC or whatever, is kind of immersion breaking for the genre of "mecha"
Super robots. That is all that is expected of mecha. Not choreographed special moveset that you have to yell the name of the move. (Gundam G)
Not timetraveling, etc. etc.
