Im going to be "that guy".
Cause I dont think its not too far of a stretch to say Neji has his ways on taking out Gated Lee.
My reasoning is based on this scan:

Now keep in mind that this was Neji's stamina during that time 1.
2. Neji should logically create a
bit larger field of chakra than he could then.
3. This move was to protect Neji, specifically from his blind spot. Not a direct attack.
So the scenario's would be a bit different here.
Now a chakra aura thats able to change the trajectory of a projectile, with its velocity to bend trees around it, and penetrated force capable of goring the earth is where I think its fair to conclude slowing down Gated Lee's blitz+plus fast strikes.
It should be enough to say that this battle could go either way.
