It will be when the power consumption will also match:

In standby, 25°, with the low speed oscillator running (for waking-up periodically and trigger an ADC readout for instance):

* CH32V003 - 10 uA - http://www.wch-ic.com/downloads/file/359.html
* ATtiny202 - 0.7 uA - https://ww1.microchip.com/downloads/aemDocuments/documents/MCU08/ProductDocuments/DataSheets/ATtiny202-204-402-404-406-DataSheet-DS40002318A.pdf
Not everything has lower than 1 uA battery consumption as requirement though.

VDDmin is also much lower for the ATtinies.

CH32V203 manual.

In the Standby mode, the contents of 32KB of SRAM can be kept (depending on the planning and configuration before going to bed), and the contents of the backup registers are kept. :)
