A_and_C: We don’t disagree too much.
Obviously: If it is not an option at all due to limited panel space, any discussion of the benefits of a 750 is pointless.
I do also agree, that if the choice due to panel space is one 750 (as only radio/nav) or a pair of 650 (which btw. is more expensive than a single 750) than it is also an easy choice for redundancy reasons.
If it’s just for the cost and panel space is available, however, I’d always argue that it is a better deal to get a 750 and keep an old GNS 430 as backup rather than getting two 650.
The only thing that I do not agree on is that a large PFD significantly reduces the advantage of a 750: Frequency lists, preview of an approach before selecting, etc. are all features that a large PFD can not provide.

He might have meant MFD here or just large screen EFIS – like G500TXi or G500…

That is exactly what I meant !
