I recently designed a board using discreet components but I replaced those chips with a single STM8 MCU because it was significantly cheaper. While designing using gates is fun, it doesn't make economical sense, even for a simple hobbyists like me. edit: one exception is using the venerable 555, but while it's a discreet component it's not a gate.
