Default Comparing t/s specs

When using the sub in a daily system on music should the specs below be higher or lower? Or is there a range it should be in? I want to compare two subs.
Here are the specs im talking about: Qes, Qms, Qts, Sd, Xmax, and Vas.

Lower qts's ate more musical but sacrifice low end without a noticeable deviation on output across its bandwidth. Higher qts's play lower than fs much flatter than low qts subs but are less transient. Mms/bl are important as well. Lower mms and higher bl's react faster so there is a personal favorite for everyone. Give either a high qes and watch the sensitivity drop and it prefer a sealed box lol. Ebp determines box type and figurimg ebp is as simple as fs divided by qes. And ebp below 45 def prefers sealed. I like to think of 50 as a midpoint between seealed and ventedd which can normally cause pleasing results from either. Once above 90 it takes 6th orrder alignments to give the driver a wide usable bandwidth.
