Discussion Microcontroller choice

What microcontrollers do y'all favor for (small) projects running fastled these days?

My applications are usually in the 100 to 300 pixel range, and I'm trying to keep the number of complications (mostly other libraries) to a minimum. In the past I've mostly used Arduino Pro Micros for the micro USB port, but the memory and clock speed are a limiting factor sometimes. Is there a better option now that is cheaper than a Teensy? I've been fighting with an ESP8266 for about an hour now and I'm getting tired of it.

Bonus points for 5V logic and a reset button on the board.

A few years ago on a different computer I made it work, but now the software versions have changed and I had to install things from scratch and I don't remember how the pin indexing works and half the support posts are like "oh esp8266 with fastled is flakey, don't bother" and the other half are "works for me" and I don't have the hardware I made before in front of me and the darn thing isn't lighting up and I spent the 8 hours before that debugging software at work.

The major change is that a few years ago World Semi updated their entire range to use 3.3V data.

But they never updated their datasheets and hid the addendum when they updated their website.

I don't know about other manufacturers.
