I want to replace my old OSes (RaspBMC and Libreelec8) for Raspberry pi B by a more modern distribution but I also I want to ensure that the performance is not much worse. As modern distributions probably are focusing in raspberry pi3 or 4, models with much higher hardware specs than Pi Model B.
Which Distribution and configuration you recommend for the the Raspberry pi1 (ARM11-700Mhz,512MB SDRAM) ?
What is the scenario of older pi models, performance and modern distributions?
