I could quote your whole post and agree with most of it. But it comes down to bad game design. Maybe the meta is shifting and Aigulac will show at the highest levels Terran is starting to dominate. The part your post is missing is that Toss is favored early game before stim and then it shifts to Terran after stim comes out, depending on how much damage Toss was able to get done early game. Damage including being denying Terran expansion and/or taking a bunch of bases/establishing big eco lead.
If you are struggling in middling level (like Gold-> low Diamond) PvT, start opening DT rush. Whiny low level Terrans are bad at scanning and think that building a turret or scouting properly is too hard so you will just dominate them. Even IF they stop the DTs from doing game ending damage, you still have map control because they wont have enough scans to push you. Plus you are going to want a twilight and blink in PvT no matter what anyway so might as well get a dark shrine too.
