Steed is British style for sure but I'd wait a bit before going down that route. You've shown photos in quite a few different RTW brands at various price points that all looked fine on you.
Highlighted the important parts of what you just said. Different doesn't imply wrong and your Formosas weren't the wrong choice by any means. This isn't even about "Nobody gets from point A to Z without some stops along the way," Formosa is Z for a lot of us, including myself. You are just used to seeing yourself in one (very very nice) style which you're happy with because it corrected a mistake you made with your first suit purchases from NM and now you saw yourself in a very different cut of suit.
Also from then to now some of your priorities have changed, you've worked out more, etc. You don't need to replace Formosa with TF or Steed, somehow - inexplicably - climbing up the price tree before nailing down what precisely you're looking for! And you can have more than one style of jacket in your closet, you know that, right?
