user70513: I was looking for a cheap MCU solution for a project, apart from being compact, ATTiny doesn't seem to provide much value. I was hoping it is cheaper but nope, They are mostly above 1.5 USD in any shop. Whereas I can easily get an ESP module for a comparable price if not cheaper, added WiFi, and optionally Bluetooth, and they are not too huge for my use cases. Am I missing something?

user7859: You can get ATTINYs for much less than $1.50.
For example, right now you can order the ATTINY202 from stock in single unit quantiles from Microchip for $0.48 each. They drop to $0.35 each at 5K units (also in stock).

If you are really price sensitive then you can sometimes get the smaller ATTINYs for even less when buying in reels at a time, but you have to shop around.
Anytime you pick a part you have to trade-off purchase price, availability (both now and in the future), and suitability. The AVR parts can often be the best choice- but all depends on what you are using it for!
