Very much agree. Scizor threatens most of the tier with 2hkos with lorb bullet punch and the high usage of tera Fairy on sweepers, along with its amazing ability to take hits, forces a switch often enough that SD can be clicked at least once per game. It feels especially strong in combination with the fast sweepers that can weaken its checks, Mewtwo and Moon being two good examples. It's also great into stall and Balance, with its Steel-type, setup options and access to Knock Off meaning it can always force progress. Some calcs to show what I mean:
