Minimizing the impact of the PU due to AM/RP or Williams performance it’s not a good argument (because in that case, the performance of AT, Haas, AR are bases for the same argument for the other PU’s).
I don’t think there isn’t much or any doubt that Mercedes still makes the best PU in the grid, this is acknowledged by every team in the grid (and every engine manufacturer).
There is no doubt that it is superior to the Renault PU, not only in terms of Power and Reliability, but also in terms of packaging (and this has been confirmed by Mclaren)... In a sport like F1 where millions are spent for small increments in performance, using the best PU if possible is the best course of action.
In regards to deployment, yes, the Mercedes PU had derating issues in Bahrain, but it wasn’t “massive” clipping as you state and most probably will be solved through software calibration more than hardware fixes.

Packaging isn't part of the PU. The different PU architectures will give you different packaging options. When RBR take the exhaust and roll them up in a way that they fit under the PU and not on the side... that's RBR Packaging of the exhaust with the requirements from Honda. If Williams, for example,where to get the Honda PU, they don't get the RBR exhaust. You don't get any Radiators with the PU. That's all on the purchaser to create.
Cooling requirements determine the size of your packaging... The Merc PU runs hotter and if I’m not wrong smaller radiators... The change in turbine layout also plays a role in how you “package” it under the covers... It has allowed McLaren for an slimmer body overall

It does, but it doesn't make it a smaller or bigger package. just a different package. Just like if you choose air to air or water cooled does as well. You can even see that, even though they're both Front Compressor/rear turbine, the RBR/Honda is packed differently to Merc/Merc. Same can be said about Alpine and Ferrari.
