It's Tenseigan and Byakugan vs Rinnegan (and possibly Sharingan), both had TSBs. I'd say they were equal before Hagoromo became TT jinch.
Both had access Truth-Seeking Balls. One had the Rinnegan, the other the Tenseigan. Aside from that, we know too little about their abilities.
Hamura since Byakugan Hamura was roughly equal (slightly weaker imo) with Rinnegan Hagoromo. If you give him Tenseigan he is a bit stronger than Hagoromo with both yin and yang seals. TSBs come with Tenseigan while the brothers didn't seem to have them pre-Tenseigan or pre-TTJ.

I don't agree with the last statement, in The Last Naruto the Movie we can see Hamura, who clearly hasn't awoken Tenseigan yet, with his usual Byakugan but already with the TSB, although there were only five of them, on separate occasions. In addition, we don't know exactly, if the shakujo, which were used by Hagoromo and Hamura during their battle against Ten-Tails, were ordinary weapons or formed by the TSB.
