Two Midrange Controls or Just One?

I have a beautiful all Koa Carvin fretless 4, an 80s bass that I have owned for about a decade. The original preamp died a while ago and I replaced it with something relatively inexpensive and didn't like the result.

Recently, I replaced the original pickups with a pair of Entwistle ones, which sound terrific. Because their output was so high, I thought perhaps that I could get away with a passive set of controls. I tried VVT, VBT, and VBT and Varitone. Nothing satisfied. Either there was too much signal loss due to loading or too much interaction when trying to dial in the tone I wanted.

So, having come to my senses, I am now searching for a high quality preamp and have decided on one of the Audere preamps. The main question is one midrange control with a switch to select center frequency, or two midrange controls, one for low-mid, the other for hi-mid. The cost difference is insignificant.

Two mid controls give more versatility, perhaps, but that's also one more control to fiddle with while playing. Generally, I try to avoid making too many changes once the set has started, but if I do have to change something other than volume, it is likely to be mid tone.

I have never had two mids before so I have no frame of reference. For those of you who have tried BOTH systems (please, not just one or the other - I would like to hear the voices of experiences, not just opinions), please let me know which you prefer and why.

Thanks in advance.

An Aguilar OPB-3 preamp has three bands of boost/cut and a selectable midrange frequency that provides flexibility to dial in just the right tone.
The push/pull midrange control offers user selectable frequencies of 400 or 800Hz, each with a full 16dB boost/cut capability.

The audere pres are hard to beat.
The 4 band is a good kind of overkill :)
The centers are well placed, and don't end up sounding hyped. I'd take a 4 band any day of the week. Noll has one too. Not sure if worth the extra money , but have not owned one.
I find the mid shift switches to be annoying.
The center never seems to be in a useful place (for me) too limiting.
With the level knobs controlling BOTH frequency, allows more finesse in shaping.
 
If I had to have active onboard mid controls, I would much rather have just one that I could sweep to tune to my pickups & ears.
I base this on my experiences with amp controls and PA mixers.
For that extra knob spot on the instrument, I'll take a passive tone knob in conjunction with 2 bands of active boost. (Not the most common layout but it does seem to have a toe hold in modern designs - with good reason IMHO.)
