TL has a +1 on ICs according to the chart. Link is -2.
Link can do a lot with
platform camping and bombs vs ICs including cover landings with bombs, which helps make up for his poor air speed. If Link bans FD, which he should, he always has a way to avoid being on the same level as ICs. ICs still have a decent way to chip at Link's damage %. His sword really isn't too great in this MU although Link can wall with Fair.
The big reasons ICs win +2 is their payoff is so high even with SoPo. Link doesn't have a great way to KO and the MU gets bad when he loses the lead. ICs have a good shot at taking the lead at any point in the MU. ICs have considerably more control in this MU. Loosing Brinstar really sucks for Link too.
None.
And even if I had played a good Link, I'd only be able to comment on the Jigglypuff/Link match-up, and maybe a few others (MK, ICs, G&W, ROB). I'm very confident that I'd win in all of those match-ups though because Link is absolutely horrendous in almost every single way.
The MU chart is good IMO; I could nit-pick a few things but I can't complain. I think if good players play MUs they almost always can agree with a +/-1 at most difference.
You're going to have to accept Link has been PRed in tough regions like NY (Kirinblaze), Rhode Island (LordXav1e, 2nd place) and other places

and he gets tourney results

And has the MU spread shown

for reasons. You have to respect other character players' experience.
Some people have played him for years and actually learned how to use him. I'm not saying he's good; Link belongs as the 4th or 5th worst character. But he can actually do things and is better than you think. For example if Link was -3 or -4 to Diddy, as you claim, I shouldn't have a
SoCal PR Diddy at 154% last stock. It's -2 Link, like the chart shows.
The first time a player plays a really good _________ character main it opens their eyes. I've had my eyes opened and taken a serious beating by many a good player of good and trash characters. I used to think Link had a +2 on Ganon before playing DLA.
The only character who gets more BS than Link is MK.
