Just so you know, this plays on equal terms with elements. Normally raw chakra is weak to elemental chakra, this doesn't count for advacd raw chakra stuff like gentle fist and the rasengan.Hmm. This a variety technique that is dependent on the users skill and intent. This technique can be used in one of two ways:
1: this is a multi-skill level jutsu that can be used to block oncoming attacks, in basic the technique is based around the release of chakra from every angle possible whilst rotting at a fast speed to generate a spherical shape that deflects attacks but it also serves the purpose as to cover a minor weakness within the byakugan.
2: with this application of the jutsu one can take the extreme defence and do a 180 flip into an attack version. The application for this is that the force generated by the rotation and release of chakra act in a manner similar to a skill involving knock back whilst also adding the elements of chakra that had the ability to physically damage opponents upon contact.
Not to mention the fact that in a multi-opponent situation this technique can be used in attack and defence simultaneously due to the basic yet overly complex execution of the jutsu.

That guide explains:
Raw Chakra
Weak to: Elemental techniques, regardless of nature. The only exceptions are when the raw chakra is molded and worked out with advanced shape manipulation (like with the Rasengan) or when it has another source mixed into it (for example, Bijuu chakra) in which case it becomes neutral to elemental techniques. Twice as weak to Dark Release.
Note: Jyuuken or Gentle Fist, is a form of Taijutsu used by the Hyuga Clan where, in some cases, raw chakra is used/produced. The same principle applies, meaning that every technique is weaker to elemental ninjutsu except the Kaiten or Rotations and the techniques similar to Gentle Step Twin Lion Fists, where advanced shape manipulation makes the techniques neutral to elemental techniques.
Also, the beauty of this jutsu is you can use it any time you want, even in the air, and it has no limit to it's use apart from how much chakra you have.
I have a cfs that uses gentle fist through a staff by the way, if you ever want to buy O_<
