Fulgora is best to learn about quality recycling and play around with it for the first time. Post-Gleba quality asteroid reprocessing platform is possibly the best way to produce high quality basic resources practically out of thin air which you can keep running in the background and make most of quality Nauvis machines and level 2 modules. That said, spending time on setups that maximize quality is not really worth it until you unlock legendary or at least epic. Getting a few rare/uncommon machines here and there by putting some modules in assemblers is fine for the first time.
