Drivability Advantages of Power FC on FD3S?

The advantages of the Power FC for the sake of performance tuning are very well documented, but I would like to learn more about the advantages of it on a lightly modified semi-daily driver. I have extensively refurbished my FD and it remains mostly stock, with the exception of a MBC bumping maximum boost to 12 psi, downpipe, and high flow cat. Overall it is well behaved and reliable but still has the occasional bout with the 3.5k hesitation despite rebuilt injectors, added grounds, and extensive other maintenance. I am considering the Power FC because I've heard it does a better job as an EFI ECU overall, including eliminating the hesitation. Can anyone outline some of the other advantages of going Power FC when huge HP is not your ultimate goal?

The removal of the 3.5K hesitation is worth the cost of it.
Having the ability to ad over boost protection by modifying the P rows above the highest one used has saved many engines.
Using negative lag at idle helps some engines to run smoother and can help power under vacuum acceleration.
The ability to lean out the idle and cruise areas of the maps keeps plugs cleaner.

Not really drivability related, but definite advantages:

To add to the above, the commander allows you to forego many of the gauges that folks install, and it aids in troubleshooting issues with OEM sensors.

You also get a pretty badass way to keep (for example) alignment shops from joyriding your FD---- just set the rev limiter for 3500 and they'll be sorely disappointed

Along the same lines, you can set the limiter for 500 rpm and the car isn't starting no matter what anyone does if you take the commander with you

Ditching the manual boost controller, since the PFC controls boost. Having the fans come on at lower temps.

Thanks for the feedback thus far guys, all good as expected. For a stockish application like mine are most using the Apexi boost control kit so the FC controls boost as well?

PFC controls the sequential twins with the stock solenoids, just put them back on and remove your MBC.
