It's all good lol. You have a pretty good Meta Knight and Robin going there honestly. Shield in my opinion is actually one of the best options against Link (especially if you know how to perfect shield).
Considering his grab is a tether it can be dodged and avoided easier than normal grabs. Even if he does manage to grab you most of his grab setups are very "read" dependent as anything guaranteed is pretty situational.
I've been a Link main for about 4 years now and I'll tell you now that going for a grab isn't really worth the risk of missing sometimes.
As far as advice goes, I'd look into learning how to deal with projectiles. Your CQC is pretty good but you seem to have trouble finding a way in and approaching.
I would advise not using Side-B with
in neutral considering it has a lot of start up and can be DI'd out of which can get you punished pretty hard.
I'd say you're a tiny bit above average, you seem to have a grasp of what to do but just need practice in executing it.
