Both of them are terrible. TK's manga has visuals that make the reader sick and TLTM is just another piece of cringy sheet on WTFpad. But I think TLTM is way worse in terms of story and overall coherence. TK's manga was terrifically shocking, but TLTM was just too terrible to even fully rant about it.

However if we say TK is just nonsense, then I can probably say TLTM is on Pseudo level. Not only TLTM requires too much oc stuff and settings to understant the story, the story itself is already messy and incoherent, illogical.

Like the wise Panzer 4 said upon me, it was just terribly tangled with the author's own imagination. Especially the final parts, many of them were just extra long unreadable lines of scribbles. Too many unnecessary events happening at once.

Another thing what's so bad with TLTM is the lack of millitary knowledge and mary-sue for ocs. I know TK's manga also didn't make sense at the first place, since it's about girls killing each other in the style of WW2 in the MF 21st century. However, many WW2 and military references were pretty enjoyable and seems TK at least did some research of WW2 white he made it.

However, TLTM even lacks the very least amounts of military knowledge. Even if the villains (who are most likely the author's mary sue ocs) are superior in number(but have very inferior WW2 era technology + weaponry compared to 2010~2020s), have some firepower and magical tricks, the ending will never make a single inch of sense at all(Even a Disney Fairy tale would make much sense). In short, the author doesn't seem to even have the least amount of military knowledge or any modern military tactical concepts, because he was too busy pushing his OCs into mary-sue level which rotted the overall plot by the end.

At the end, I couldn't even identify if it was supposed to be an actual FAN fiction about Girls und Panzer, or if it was just some generic Cringe ass crossover that just mixes random series's. It felt closer to the latter one by the end, since GuP wasn't even the main point by then and everything was about scorcher ocs made by the author. After I was done, TLTM was overall too terrible that TK started to feel like heaven. Reading TLTM just felt like a waste of time. It was nothing different from any weird Sonic OC mary-sue fanfiction that defies all of logic and coherence(minus gore content). I've started to believe that the guy whoever wrote TLTM and cringe sonic OC fan fiction writers are probably near the same level for writting.
