I think Uchihas also posses massive reserves of chakra like the Senju.

[Tyrance sasuke]

Without enhancement they doesnt have big chakra pool.

Indra inherited chakra from the sage. Unlike asura. Naruto has immense chakra because of kyuubi. Sasuke has immense chakra of his own as chidori usage cause plenty of chakra.

Indra inherited chakra from the sage.

He inherited powerful chakra, not big chakra pool.

Unlike asura. Naruto has immense chakra because of kyuubi.

According to third databook Naruto has 5 in chakra while Sasuke only 3.5 And databooks counts only base stats without Kyuubi, Sharingan etc.

Sasuke has immense chakra of his own as chidori usage cause plenty of chakra.

Without Kyuubi Naruto was able to use SM which takes a much more chakra than Chidori.

Are you sure databooks only take base stats? And prove chidori chakra usage is lower than sage mode using.

Yes. Otherwise Naruto wold have 5 in all stats except hand signs

And prove chidori chakra usage is lower than sage mode using

Without big chakra pool you cant learn SM. Even Jirayia which had 5 in stamina couldnt achieve perfect SM.

[FemmeFatale]

Sarada reserves are pretty high

 

[Reviewing Logic]

Sasuke and Indra were an exception to the rule due to be incarnates

Itachi dead overusing his MS and Obito could only pull of PS due to his sage of sixth chakra he received when becoming a 10 tail host

That moment when Naruto's base reserves and stamina was being increased by Kurama's chakra since he became a jin.
