A keyboard's sound depends on the case, the caps, the plate - if any - and the switches. Probably in that order. Your preferred switch will sound different with combinations of the other factors. In my experience, the case and plate make up most of a given sound result. Their material and how hollow is the case account for the lows and highs of its sound and its volume. The caps also give the final assembly its particular pitch. Regarding switches I have observed that clicky type adds its own noise to the typing, while linear and tactile don't.
I'd say; Choose your switch, build your board and be surprise by the final result.
Edit: One more thing: You asked about the best sounding switch. In who's opinion? You are having different recommendations because each one is giving you a personal opinion. By definition, your opinion will be different than ours. Bottom line: Try it by yourself.
