Fairy Tail spin offs

Okay with all the crap we give Ikemoto for his boruto spin off where ever compared to kishimotos early chapters of naruto is pretty bad so I decided to research and compare how fairy tails spin offs compare where if it wasn't obvious just about all of them where including these 2 , ice trail, and twin dragons saber tooth were done by different artists approved by Hiro mashima. Now these spin offs unlike the boruto manga didn't try to do anything crazy like basically retcon what previous protagonists did in the main series but they do expand the world in the sense the main focus is on other characters. Twin dragons obviously about rogue and sting, ice trail all about gray, ur Mistral are Wendy adventures, and fairy girls all about the sexy ladies of fairy tail doing what they do best. Save the world or solve cases on their jobs by using fanservice and some action inspired by the main series. lol I guess in a way these spin offs while the art styles have slight differences compared to hiros you can definitely see they actually tried to stay as close as they can while adding their flare to sell them as separate series aka spin offs so as not to influence hiros main story unless he feels those earn a spot for anime TV. 2 spin offs give background and more to learn on others whole 2 provide humor and fanservice.

I think had kishimoto done something like this during narutos run where he gives the info or worked with others to keep tabs on his side characters then perhaps there would have been similar spin offs on your favorite naruto characters and as seen with most reactions changing the art style to a whole other genres does not work well for others.

What do you guys think? If you were to compare Ikemoto to these other 4 artists who did fairy tail spin offs or even kenjis spin offs of naruto SD staring rock Lee or sasuke and his reality changing sharingan what do you all think Ikemoto did wrong. I have seen and heard but I would like to hear how compared to others who have done spin offs to a series whether for character or world expansion or laughs what did Ikemoto do wrong compared to them. Even freaking junior high attack on Titan did a better job as a spin off.
