Super #17 is worse. FnF may have shit like Roshi fighting in the battlefield, but at least that's funny compared to the cringeworthy contradictions in the Super #17 Arc.
Yep. I'd say powerscaling in Super #17 is even more screwed, because due to Freeza training, you can just infer Shisami in the movie trained with him like Tagoma did in the Super anime. Meanwhile Super #17 arc has:
Villains being able to create a Machine Mutant, alive and "one" with the #17 on Earth with no laboratory equipment, and despite the fact that Majin Vegeta's death stated in the anime that they end up in a different world than heroes and normal people do, with no functioning bodies and are waiting to be reincarnated as new creatures
SSJ2 Vegeta being massively above Super Oob for no reason despite Super Oob displaying far better feats against SBV2 than SSJ3 Goku did, and Goku not getting noticeably stronger after getting his tail restored. And somehow SSJ Goku gives #17 a better fight than everyone else combined. This could've been explained had they said Vegeta and Goku's experiences with Golden Oozaru and SSJ4 caused their full potential to be partially manifested in lower SSJ states similar to Goku retaining SSJG's power in base/SSJ in BoG, but nope
#17 is stronger than Trunks even without fusing, with no explanation while #18 is largely the same strength and gets one-shotted by his blast. Yet she gives the SSJ4+ tier post-10xKHH absorption Super #17 a huge energy boner when she Ki blast spams him
They try to revive Kuririn with the Earth Dragon Balls immediately after the villain is killed
All the villains are alive with fully living bodies and end up just sent back to Hell when killed, despite that completely contradicting how afterlife bodies were supposed to work in Z. And Freeza and Cell in Hell are repeatedly restored to life when destroyed for no reason as well, rather than it being explained it is part of the torture that villains in Hell go through as part of their punishment
Among others I may not care to remember because the S17 arc was such trash that it's filler worse than Garlic Jr. and Paikuhan.
