Simple anyone who’s used both was one better than the other (pros and cons of both)? I imagine the oil might last longer throughout the day. Lastly how do you find the purposes for mixes that begin with “P” or “M” or “T”?
If you want to use it for status in work/professional situations, oil is far better in almost all ways.
Longevity, subtlty and complexity in effect particularly and far more economic in the long run.
Spray is fine as a try out and it is more present which helps in some situations but I largely keep it as a topup/refresh to use in support of the oil on long fays or when I get called to work with the big guns.
As for the rest - you don’t. You try them and report your findings back to us. There are experimental products or variations on existing ones that are still under evaluation - which is why they are sold without claim or warranty. A quick search will soon turn up other people’s findings.
