It's one of those subjects where there is really no one size fits all. But I am certainly of the opinion that the claim that longer scales 'automatically' mean more comfort is unhelpful, as that claim avoids the variables like:
1. size of the persons hand
2. Length of the persons fingers
3. Mobility of the person
4. The width of the string spacing not necessarily following the increase in scale length
5. The profile of the neck itself
All these things vary. What I do note though is - the vast majortity of 'my fingers don't fit' complaints I see (if not ALL) are people strugglng with things like 3 fnger D chords or others that involve putting more than one finger next to each other on the same fret. Increasing the scale length alone will NOT help that, but increasing string spacing will. If anything, if you make a tenor with a narrow nut (and I have reviewed one by Snail) you don't create any advantage in lateral space and then add in the increased other issue of longer stretches in other chords.
All in all - it's far from a one size fits all. But in my experience - for 'most' people, it's nut width that matters more - they just dont realise that is what it is because generally larger scales have wider nuts and they think its the larger scale that sorted it. But that's kind of a consequence that doesn't always follow. I have played sopranos with more neck space than some tenors!
But yes - what is comfortable to you is what matters. I can only advise generally and do so based on what I find is the most common likely solution. I do point out that it varies though
