Compared to nRF52840(same ram/flash/packaging), this is nearly a millimeter smaller x/y, 3dB better sensitivity, 2.5x faster ADC sample rate(but who knows what that means with a +8dBm radio firing near it), and hopefully not botched readout protection. No USB though, big deal for some.

I'm not familiar enough with the nRF54 series, but it's good to have a few competitors in this space.
