Bang for buck is usually an objective measure based on the number of features per dollar or relevant currency.
Bang for the Buck ≠ Personal Value
Pro models do not necessarily offer "extra features" they offer "premium features". So, as much as we may prefer the Pro models, when quantifying "Bang for the Buck" then the 'iPad experience' is not weighed higher than the iPads ability to perform equal tasks (not tasks equally).
For me, I dont like the standard iPad. It feels so outdated. But in actual use then for $300 dang is that thing a capable machine.
Actually, bang for buck is whatever I am decided is worth spending my ‘bucks’ on, isn’t it?
Sure a basic iPad is good value, no denying, and I can do stuff on it for sure, but for what I want it’s a complete waste of 350 quid. It has low end features which have either no benefit, or are detrimental to what I need. Being good value is not the same concept at all.
Now, there is no denying I can do what I like with a super awesome 16” MacBook Pro and a Wacom tablet. Whizz bang boom. Fast, powerful, high spec.
But - a thousand plus a few quid 12.9 iPad Pro with a pencil? Best mobile screen available, plenty powerful, portable editing machine plus laptop like functionality coupled with iPadOS features? That’s by far the best bang for the buck for me.
Say what you want - but there is no denying bang for buck is highly subjective.
