Arduinos are development boards, right? You develop something fancy. When it's ready, do you leave your Arduino attached or even soldered to your fancy quidditch playing drone and buy a new one for the next project? Or do you remove the Arduino and replace it with a bare microcontroller chip? Is it even worth it?
MY Arduino boards are all Nanos. when a project works, it's done, until maintenance is required. I never buy a new Nano, I buy 3-4 at a time, so at least one spare is in the drawer.

I have made several projects using 8MHz Atmega 328 chips on stripboard. I don't think it ever occurred to me to consider the nano as an alternative.
I also have some small projects with Attiny84s and Attiny1634s - but they are so small there is no space for a PCB.
I don't currently have the knowledge to design a PCB for surface mount devices and I don't have sufficient need for them to make it worthwhile acquiring the knowledge.

I use teensys. Buy them like potato-chips and and solder them into everything.
Anyone use https://www.expresspcb.com? I don't hear about it much anmore but back in the day I used the heck out of this PCB service.

Most often I use a bare mega328 or tiny85 usually running at 8MHz. The chip in a socket and all soldered up on proto board with the other components.
I make up PCBs with all the circuitry of the project.
Hi,
I like others, but lots of cheap Nano, Micro etc.
My PCBs and prototype Veroboard have headers to plug them in, makes development and final construction so easy.
