I've decided to play through Red/Blue with different parties to get a better grasp of who really is efficient.
I just finished a run. Here are my thoughts on the Pokémon I used:
Charmander: my starter, used up to level 29 and boxed before Rock Tunnel. In the early-game I think he's underrated as a starter--what he loses in inefficiency against Brock (whom he can still solo anyways) he gains in being the best Bug-killer and having the easiest time at Mt. Moon. Ember is a great attack. However he hits a mid-game rut where the other starters have learned better moves and he's still using Ember, and this inconvenience led me to ditch him this run. He's efficient at times, but he's not top tier.
Pikachu: the early-game star. Pikachu is surprisingly self-sufficient as long as you have a teammate to kill the rocks. There are parts of the game where Pikachu can gorge himself silly on Water- and Flying-type Pokémon (S.S.Anne is one such area--I think my Pikachu grew ten levels there). Most other enemies still dislike a STAB Thunderbolt and even Grass-types and pure Grounds can be dispatched by Swift. You can evolve him pretty early, too. Raichu's strength fades at the very end, but not by much--he's still helpful in beating Lorelei.
Abra: once Kadabra gets Psybeam he slaughters the entire middle-game. I'd be surprised if any Pokémon is half as efficient as he is.
Tentacool: my Water-type. What's useful about Tentacool is if you catch it at level 30 he already OHKOs the wild Fire-types in the abandoned mansion. That way you can simply put him in the lead once you hit Cinnabar and he'll level himself up to the rest of your party in no time. Other Water-types aren't quite strong enough.
He also gets better coverage than the other Waters due to Mega Drain. In a pinch he can take on Lorelei if your electric-type faints. Fortunately my Raichu didn't, but Tentacruel was the Elite Four MVP anyways, beating most of Lance and Gary's teams (and Bruno, but anyone can do that).
In this run I aimed for a team I knew would work efficiently. Next time I'll go for a similar but weaker team. I'll get back on how well various Pokémon work.
