I also have read the entire thread, and I agree his towards you wasn't the most ridiculous. He just thinks he is edgy when in fact he is a detriment to the community; I wish someone would curtail it, and I often wonder how many new and potentially progressive players have not posted due to fear of being ridiculed. I wanted him to realize perhaps that he shouldn't pounce on people's simple mistakes since he also makes them
Anyways, back on topic... I feel both fox and pika have the same problem, lack of guaranteed kills. (Most characters outside the top few have this problem, FWIW). Pika makes up for this with great damage racking, a great projectile, and strong possible gimps and edgeguarding. Fox makes up for it with decent jab set ups on some characters, and his always potent running-usmash. Both characters are more likely to be hurting due to rage than benefitting, as they die before the true heavies. I think pika has a slight advantage in forcing mistakes due to tjolt's superiority over the laser (much more mobile, damaging, and often leads to easy grabs which put us in a strong advantage state), but his weight is worse than fox's (although fox is taking more damage to juggles than pika, offsetting this).
I think their relative placement will come down to how they handle the top tiers, and I think pika wins this. Perhaps this is more a statement of my region, but I believe that good MUs against Shiek/Diddy/ZSS/CF/Luigi is more important than the rest of the cast combined, and I think pika has a leg up on those.
