That's an exaggeration. Being Psuedo Jins had nothing to do with Kin and Gin's Base Level of Strength.
Those weapons are essentially useless if the opponent can't tag their opponent. The only reason Darui was tagged was based on Darui's concern over the hostage (don't care about her name), so it was only a useful tool against fodder unless you're quick enough to tag your opponent which Base Kin and Base Gin were not without some form of distraction.
You interpreting them as god tools is a complete fallacy. They're amazing tools used for sealing souls and prevents them from escaping, but that's essentially what they are. They're useless when you can't even tag your opponent with the rope first.
Yes it did because Kyuubi Chakra naturally mixed with their own and became their base chakra, thus the whiskers on their face, and with all that base chakra they can spam weapons that normally kill average shinobi if they use them. So yes, being pseudo Jins increased their base power, dramatically.
The weapons are only as good as the masters. You already know how fast Tobirama and the Raikage are in general, or you should at least. Yet somehow they survived their speeds and wasn't shitblitzed instantly with Hirashin Giri. What does this means? The bros weren't slow by a
long shot and they had the speed to hit people with their attacks, even Kages like Tobirama.
You're not even using "fallacy" in the correct context. Sage of Six Paths is a god. Treasured Tools were his personal weapons. They were a gods tools, which makes them God tools...... One can create all 5 natures, one seals you away with as little as calling your name, and the others take your soul and seals you. Sounds god level to me buddy.
