No offense, but aren't you just buzzing about Pikachu now? Somehow I suspect if we were all like "Pikachu is too low on that list, here's why" you'd have been fine with it.
I think that you're mistaken (or have misunderstood) on multiple levels, but here's a quick few:
-I'm posting about Pikachu because I want to stress that he's very good. It has nothing to do with the tier list. I've been posting about him since the invitational.
-Of course I would have been fine with it if everyone were simultaneously talking about Pikachu's tier list position and why it's too low. That's the entire point. That would be a focused discussion. I would also be fine if we were all discussing Dr. Mario.
-I have no bias for my characters, if that's what you're suggesting. If I realize that they aren't as good as I think they are, I will switch mains for tournament. I understand those who have character bias or attachment, but I'm not one of them. My favorite character is Diddy Kong, but I don't like how he plays at all. A character is just a visual representation of a toolkit to me.
-I don't necessarily want the discussion to be about Pikachu, but I obviously have more experience with Pikachu than with everyone else, having mained him in Brawl (you can ignore the "MK" icon in my profile, that's a joke on Brawl's MK dominance). If I can post useful information in this thread, it will most often be about Pikachu, or characters I've fought against as Pikachu.
That said, I too am guilty of tier list buzz where I made a post earlier in the topic discussing characters which were out of place (in particular Mario), but looking back at that post I don't think it offered much to talk about. I don't mind that we've been buzzing, but I think that Locke_06 is right, it's not the most productive discussion.
Anyway, as for Pika specifically, I feel like he's still pretty much the same character he's always been. Fast, annoying, good recovery, UpSmash kills surprisingly early. His range and kill options are his two biggest weaknesses.
I don't think that he has problems with killing. f-smash is disjointed and reads are hard to punish (his smashes all have quick recoveries). Up-smash is as good as it ever was. Dash attack now kills, albeit at high percents. Thunder kills, you just have to make it hit Pikachu's body. f-air is often a kill confirm.
Offstage gimps are where it's really at though. This character only struggles to kill if you are afraid of his options.
As I mentioned earlier in the thread, he's the same character except for a few things:
1) Quick Attack now hits you and hurts, so it's a good approach that isn't reactable
2) Better offstage game, if you can believe it
3) Ice Climbers, Olimar, and Meta Knight are essentially gone, and Diddy Kong has lost his double transcendant bananas, which is huge, as they all had unique mechanics that shut Pikachu down in various ways (MK was OK though, in fairness).
