Rikage's are top shinobi when it comes to chakra
Kisame take's next place after Rikage's
Kushina should be above or below Rikage's ,she blessed with most powerfula as wel as high chakra level's amoung Uzumaki,a half dead Kushina is able to bind a ful pwrd Kyubi like it was nothing ..
Hashi's chakra reserves aren't as high as ppl thought ,his chakra control is same as that of a god tier which means that he can use any Jutsu wit min amount of chakra and his chakra level is dfntly > all Uchiha's
Naruto take's next place after Hashirama (or may be he is a bit above Hashirama) due to Obvious reasons,he showed god like chakra level's even though he suked at Chakra control
Madara should be below Hashirama and Naruto
U can't compare Nagato with Rikage,Nagato is dfntly one of the best but his chakra level's aren't as good as Rikage's,HE absorb's chakra with pretha and can use it that's y most of the ppl are thinkng like that........
Jman surely had high juice level's but he is nowhere near an uchiha or a senju....
Tsunade >> Oro as wel as Kabuto
Minato >/= Oro
Sasuke > Oro
Obito > Tsunade and Sasuke
Saru shouldn't be there in top ten same goes for Minato...
We dnt knw abt Tobirama but surely > Tsunade,Oro,Minato,Kabuto,Nagato and Jman
In my openion
The list should be like this
1.4th/3rd Rikage
2.4th / 3rd Rikage
3.Kushina
4.Kisame
5.Hashirama/Naruto
6.Hashirama/Naruto
7.Madara
8.Nagato/Obito
9.Sasuke/Tobirama(may be abit above Sasuke)
10.Tsunade(With seal on her forehead Tsunade is abit above ir equal to HAshirama)
