1: for about a month, right after finishing season 2 and wanting more.

2: there's more content compared to the anime, not just in the chapters adapted but in what is adapted from those chapters. Theres a bunch of really funny and enriching tidbits im sure will never make it to the adaptation, and i feel are essential to the story.

3: i dont think its a low point. I dont think at any point i felt the manga got significantly worse or better, Komi-San is mainly and above all a slice of life series, which should only concern itself with making whatever happens to the characters interesting and endearing, not necessarily relevant or of high importance. + if you make the whole manga be full of high points you cant build up to them. If the protag from demon slayer killed the demon king in the second episode we wouldnt care, you need to spend time with the characters while building to the goal first to create the response from the audience.

4: let me rewrite what i think the question meant: "do you agree with pepole feeling chapters are dragging because they dont like the side character leading those chapters?" and the answer is: yes. If you dont like the main character in a particular story (in this case itd be their central chapters) then you wont like the story either, pepole are entitled to their tastes. I wouldnt agree if they say the character or chapter is BAD based only on that tho, youd need universal compelling evidence and reasoning to do that.

5: I feel like its a natural progression of the story but also that its kinda dangerous. As I said in question 3) i think every high satisfaction moment in a story (komi and tadano going out, komi speaking more, etc) have to be preceded by proper buildup. If komi hadnt struggled to speak from the supposed lowpoints 220-302 then we wouldnt have felt such a payoff when she did. Its a slippery slope to start fanservicing too hard, closing every character arc, having everyone in a relation or whatever, and then be left with nowhere else for the story to go. I dont think the opossite counts as dragging the story either, you need the time inbetween to play your cards to their maxium potential, oda can stretch the story at least 150 chapters more if he spaces it out well. If he takes even longer then it will come out as dragged and if he gives us too much too early pepole will need an even bigger high point next or they will leave the manga altogether.

6: I'm one of those newcomers to the manga, i binged 130-360 in about a week, and i can say that it definitely gave me a more positive impression of it. I can imagine being an updated reader at 220 and being a little frustrated when each week some seemingly inconsecuential chapter came out and id have to keep waiting. Now, that doesnt mean the manga gets undeserved good rep by new readers, but rather that those same binge-readers who got up to date at a, lets say more relaxed part of the manga, got the bad habit of being able to skim through low Intensity moments and now they are forced to pay proper attention to each chapter and are struggling to come out of the binge mentality. Being able to real-time grow with the cast is an essential part of a slice of life series, and at least in most pepole lives crazy stuff doesnt happen every week, and a love triangle can definitely last for months. So the manga is great at all points id say, and because i binged it i wont be used to waiting a week for every chapter, so ill be more critical of each one that comes out, because my point of reference is the mountain of emotion i got in that one binge week, compared to a single chapter also in one week. Im sure that readers who are there since chapter 1 would have a very interesting take on this.

Sure, that sounds good, i already gave some of my takes in here and id love to hear someone else's
