"Byakugan User" is too broad. It automatically qualifies Kaguya and Momoshiki. The former outright reacted to it and evaded. The latter could freeze time.
You should change your title to "Hyuga" instead of "Byakugan User", because we all know that's what you have in mind.
Anyway, FTG is deadlier in these cases, because it maintains momentum even after teleporting. FTG version II depended on this nature to for its effect.
Ameno doesn't, and brings Sasuke back to zero velocity. He has not been shown to 'maintain' momentum after using Ameno. He always uses it to appear right next to opponents or to evade.
So, Kaguya would have had a harder time evading an FTG combo.
Momo, on the other hand, could still freeze time and get out of the way, I guess.
All of this is assuming that Momo can actually freeze time while alive, and that he was restricted from doing so by plot during the fight. I mean, who gets an ability after death?
