Oden could control Oden’s free power up casually, while Pinzoro didn't even know how to do so- and it's only this chapter where he manages to finally tame it and the powers of channeling that come with it, with us the readers learning that up until now it was mostly a hindrance and actively very hard to keep under control.
Does that mean he's at Oden's level? Honestly, just depends on what's your perspective of Oden's level is.
But what's set in stone is the narrative given us to us which well let us know when Pinzoro will surpass Oden. Pinzoro's progression towards Oden's level and beyond is dictated by Oden's very sword, and there's only one thing Oden, himself, was not able to do:
It's the narrative set between Oden and Pinzoro in particular, because Oden’s free power up represents the climb, controlling Oden’s free power up represents doing bare minimum of what Oden could always do, and turning it into black represents surpassing him to the narrative these portrayals have set. Does this also mean Pinzoro will surpass Red Snitch or whoever doesn't have black blade? No lol.
The narrative given to us binds these two characters with this sword, not every Swordsmaster (does not include shanks) out there.
