1) Danger detection isn't an active power. It is a passive power and definitely dependent on your raw potential (Leia and Han for instance use it without being taught how). Yet Anakin stumbles into an energy cage. 2) When Anakin and Obi do the force push against each other, they are at a standstill. Force push is definitely something that is amplified by anger. Anakin was supremely angry, moreso than Vader usually is. Yet he didn't manage to push Obi-Wan back. 3) The Padmé choke he did in full rage mode (so we can say the dark side gave him full power at that Point) was fairly weak. It didn't even kill the target (compare how long it took Vader to kill Ozzel). Therefore, Anakin Skywalker was portrayed as underpowered. He is obviously far inferior to Vader in both skill and potential.
