I don’t own a ST yet, but based on the Elektrons I do own (MD, MNM, OT Mk2, AK):
From a financial perspective, Elektrons start out feeling a little expensive. There are various sales, and then they drop in price further after they are discontinued. And then there is a slow climb in value that spikes when Autechre or another act That We Like touches it (or reminds us that they previously touched it once). From a utilitarian perspective, Logic is all you need. From a fun / workflow / creativity perspective, Elektrons are always good (for me). Worth $1k? Probably. Depends on your budget though.
I have a TR-8s and enjoy it even though I have the famed MD Mk2 UW+. I would prefer not to give up the TR-8s or the MD.
Only you can tell if you made the right choice. There is very little truly bad gear out there.

As the A4 thread suggests, any Elektron can be a drum machine if you try hard enough.
