There were other good/decent storylines in SWTOR. The only good thing about that game were the class stories, but you have to slog through a terrible MMO to enjoy them so it's questionable if it's worth it. I played through every single one, and while they were fun, man it was a huge time expenditure. Only worth it if you have a ton of time on your hands and nothing else to spend it on.
Also your class summaries are pretty bare bones and you miss their appeal. You also didn't cover the crews which are a big part of the fun of the game.
Jedi Knight: It really is a classic Jedi story. The light in the darkness fighting valiantly against the forces of evil, totally vanilla. The only thing going Dark Side does is make you more brutal when dealing with the Sith or other villains, instead of attempting to redeem them or imprison them, you just kill them. Whether or not you enjoy this really comes down to whether or not you like vanilla good vs evil conflicts.
Crew: Pretty dull assortment. T7 is the plucky droid sidekick, Kiras the rebel without a cause, Doc is literally Hawkeye from M.A.S.H, Rusk is the "sole survivor" archetype, and Lord Scourge is the "villain with standards". They're all pretty basic tropes and all pretty bland.
Jedi Consular: This storyline was weak. Very slow, very uninteresting, and lackluster from start to finish. You more or less go from being an archaelogist to a diplomat to a redeeming priest and none of the three are done well, or are compelling. Easily the worst storyline on the Republic side.
Crew: Qyzen was great, he is honestly the best part of the entire Consular class. Tharan was at least an interesting concept, Nadia is just the super gifted prodigy that seems to only exist so the Consular can have a female romance option, and Fenix/Zenith are totally forgettable.
Commando: I actually enjoyed this storyline. You can either go scorched earth the mission over everything or play humanitarian soldier. The missions were well put together and it was a solid experience. Nothing spectacular but it was good.
Crew: Really good crew, Aric is great, Elara is fun, and M1 is the best droid companion in the game. Yuun is fairly forgettable, and Tanno might as well not exist.
Smuggler: The most fun I had playing this game, especially the first chapter. They did a great job with this class, I loved the missions and I loved the interactions. Dark Side is way more fun than Light Side.
Crew: Easily the best crew in the entire game. Risha and Akaavi are fantastic, Corso and Bowdaar are bro tier. Gus is hit or miss, you either love him or hate him.
Sith Warrior: Pretty good, either play as a competent Skeletor, or a reformer who wants the Empire to succeed by ending the stupidity of the Sith power games.
Crew: Garbage. Broonmark is the only decent character in the entire lot, and he barely speaks. Pierce is just forgettable, and that's a cut above the rest. Vette is annoying as fuck, and makes no sense as a companion the way she's written, Quinn is more of the same, and Jaesa is either a Jedi with zero personality or Edgequeen McEdge.
Sith Inquisitor: Absolute worst storyline in the game. I regret spending the time playing through it. Every other class gets multiple threats that wind up to the big threat, in the Inquisitor storyline you fight the same guy I think it was, three times? But he keeps surviving or getting away, it was saturday morning cartoon tier in its execution. Nothing about the story was engaging or interesting, either, absolute trash.
Crew: Khem was good. The rest are trash. Xalek might have been interesting except you get him so late he may as well not exist as a companion.
Imperial Agent: Already covered, really, fucking awesome all the way through. Everyone should install TOR and play through this, it's so much fun and really immerses you.
Crew: Really fucking good sans Raina, who felt out of place and forced. Kaliyo, Vector, Lokin, and SCORPIO were all great.
Bounty Hunter: I actually really enjoyed this. The way you work up from small times bounties to the final mission is great, and you never lose the theme of seeking to become the best in the galaxy. This is kinda like the Jedi Knight though, in that you have to possess an appreciation for the story type to really enjoy it.
Crew: Pretty good. Mako is a sweetheart, Gault is god tier, Blizz is fun, and Skadge/Torian are forgettable.
TOR really is a tragedy. In a lot of ways it had so much potential and a lot of glimmers of greatness, but in the end it was a game stuck being a shitty MMO. People always point to the later Mass Effect games or DA2 as to where Bioware died, but I think the real reason the company fell apart was TOR. They lost all their best people after it flopped and all they have left at this point is the name of the company.
