i would watch all of the above. with discovery at the very least the first four seasons, because S2 is a backdoor season 0 of strange new worlds and S4 rocks but needs the context of the first 3. it can be very uneven but i don’t think it gets bad as often as Picard did and doesn’t stay bad for as long as Picard does. Enterprise is similar, a rough-at-times ride that does really pay off in S3

you’re only gonna watch one, though, i’d do strange new worlds. it’s essentially a return to the TOS/TNG format and has a stellar cast. and frankly you don’t need to watch disco S2 to fully know what’s going on, they explain everything- i only watched disco after snw S1 left me hungry for more. SNW is seemingly unique among trek shows in that every season has been less well recieved than the last, partly because the short seasons are increasingly dedicated to gag episodes, but i’d say with the exception of one particular stinker in S3, a weaker SNW episode is still gonna be better than most shows at their best

but also- you’re your own person and may walk away from all of these series feeling someghing different! no harm on trying and if you hate something hey, it only cost you 40 minutes of your life
