Side by Side Comparison Aguilar OBP-3 vs Audere Classic 4

I know that this has bee covered ad nauseum before, but I'm looking to replace my Tome Pump Jr in my Spector ReBop 5. I have the stock EMG Hz's.

It looks like there are more Aguilar fans here on TB than Audere, but has anyone actually heard both these pre's in a Spector in a side by side comparison? The Audere looks to be cheaper and comes pretty much pre-wired. The four band EQ on the Audere looks nice but I'm not sure if I need it or not. I love my Spector but I often get frustrated trying to find the right tone. Others have commented the replacing the Tone Pump made a tremendous difference. Your thoughts.
