depends on a user.

first some ability aproximations (small number of people use scorpion's, but it is important to remember that it is a new trigger compared to kogetsu): senku=mantis; senku=throwing scorpion blades; genk'yo=mantis; durability+power of kogetsu=flexibility/unpredictability of scorpion.

in aerial and in-water fight scorpion has the advantage because the blade can be sprung from any part of the body so the orientation of the body is irrelevant, and can be used to swimm or change direction in air - for all of this we've seen exaples.

someone with agility and ingenuity  and small frame will benefit more from a scorpion. although there are exceptions; for example it's a better fit for yin than kogetsu because its flexibility is a better match for his side effect (future constantly changes in a fight so a flexible weapon is a better, more usable choice as it gives him more options from which he can choose the optimal one).

forget about popularity and even about the raw stats. what matters is who uses it and how. don't forget that scorpion is a new trigger so it really didn't even have real masters (who could show its power/value); haven't really caught up yet with the agents. yin was/is the first master (and inventor), but more so because of his side effect (it's not his mastery with scorpion that makes his strong; even though I don't doubt that he would be strong even without his side effect, it most likely wouldn't be top 3,5 attackers; he haven't really used it to its full potential and from his fights I get the feeling that if he didn't have this specific side effect he would be more suited for kogetsu)- he is essentially no2  if you take into account his fights against tachikawa but nontheless in top5 attackers. than you have kazama who is extremely agile (no2), kageura who invented mantis and had over 14000 points for scorpion (ex no3 most probably) and than you have kuga who copied all scorpion abilities and will eventually become the best scorpion user overall (maybe not stronger that yin due to his side effect but a better scorpion user)- and is now based on his exploits, easily in top10 attackers. so now you have situation where appart from ko (who is only half kogetsu user), tachikawa and his teacher and tamakoma 1 (but the question is how good reiji and kyosuke would be with standard blade triggers; Kirie's trigger is close enough to wielding double kogetsu) best attackers in all border are scorpion users.
