Yep this has a lot to do with personal preference.

If you think about it, there is only one kind of technical argument with a firm basis, namely that a film accurately reproduces the colours on a sep chart under particular light. So then the issue for us real-world photographers is: what happens if conditions aren't exactly those of the lab environment... too much or too little exposure, colour temp not quite 5000K, lens rendition a bit off neutral, processing times a bit inaccurate etc.
