I guess I am comparing them more to arduino / adafruit replacements, rather than more direct manufacturer prices. I have no experience with Nucleo boards but many other boards I tried out just hadn’t no community or body of libraries to draw from, whereas the teensy is pretty popular in the makers community. In my case I happened to need to drive 1,000’s of LEDs in real-time for an art piece and not only is there good software support, there is even dedicated hardware made for the teensy for this in the Octo Ws2812 board. I was so impressed with the quality and the size that I generally just use a teensy LC even when a $3 trinket would probably work. YMMV

I hear you. Check out the EPS32 [1][2]. It's faster, has more mem and has built in wifi, so you can access a webpage[3] on it via an ip and your browser and remote control it via your phone. FastLed runs on it, and there are level shifters similar to the Octo for it [4]. You can actually run 16 channels I believe (vs 8 on the Octo). It uses the same level shifter (x2) as the Octo. There is also an 8 channel available if you check the other products on Jason's store on that Tindie site[4]. It's arduino compat- so you probably wouldn't have to rewrite much at all.

There's an online IDE (which is similar in many ways to Arduino) with a whole ton of libraries, accessible from a, well, library, rather than having to hunt them down.
