We have to preserve the purity that is the Goku and Vegeta show
Toyotaro is doing gods work
More like fans being salty at anime Future Trunks and says he's a Mary Sue. So they enjoy manga Trunks getting his butt kick.
I will somewhat defend on this. Toriyama obviously didn't give Toyo and Toei much to work with other than Trunks having Super Saiyan 2 and some techniques from Gohan and Vegeta. Toriyama also wanted Trunks to get the 'killing blow' given that Trunks cut Merged Zamasu in half in both versions. But he never gave Trunks a big power up, hence Super Saiyan Rage and Super Saiyan 2 Trunks being even with Super Saiyan 3 Goku in the manga.
Toei may have taken it too far (YMMV), but Toyo went too far in the other direction, imo.
But the biggest disappointment in this arc in the manga, there was no emotional impact. To be frank, I didn't care for anyone in the manga, not even Trunks or Mai. While in the anime, I felt real sadness by the end of the saga.
