TNG then TOS, then release order is the best TBH. you can throw in TAS whenever you want after you've seen TOS. I's good for when you're high. don't listen to the people who tell you to skip enterprise it's good. watch the frist two seasons of discovery, then you can watch more discovery or strange new worlds. lower decks is any time after voyager, which is during or after DS9 which you must have seen TNG for and TOS for maximum enjoyment
