Ya I can see that. I do try to jab out of CC sometimes but unless I am on point I find it really hard to do at good times. Your opponent can CC punish your jabs, too. CC run away / roll are also solid options.
Anyway, I have not heard anyone say anything bad about Link's jab. Link players love that move lol. Maybe it does get forgotten or end up under-utilised, but it is not under-appreciated. Though I should note that I've had my fair share of bad times when using too many jabs or throwing them out too willingly.
Ganon's jab is faster and has something like spacy f-tilt knockback, so it is much safer and connects in more situations (except where range is a factor).
No, yea I consider Ganon's Jab much better and much more useful against top tiers (that's why I did not compare his like I did Samus and Marth). I just used the CC example since it is sort of similar in that situation and Ganon mains seem to actually use it well.
But the thing is that they cannot react to Link's Jab and even if they did CC the first or even second hit they would still not even be able to react with anything fast enough that could reach. Actual reaction time is 25-30 frames in a match, everything else is pre-emptive or a read (Axe, Armada, Mango and DruggedFox I notice have super human reaction times). Both jobs also do decent damage, so using it in different variates (Jab1/Nair - Jab1/2/1 - Jab1/1 - Jab 1/2/1/2/follow-up) as preemptive anti-approach, out of CC, mid-close pressure, following SHFFL, etc can rack up some damage, control the pace of the match, and even lead to openings.
Now of course you can't just stand there and Jab 1/2 over and over, but you can usually get away with 2 pairs of Jabs (or a 1/2/1) before they can retaliate, often you can see them get pushed back and see an opportunity to land a D-smash, Grab or even slower moves like D-tilt and F smash at that point.
I guess what I'm trying to say is that it's sort of well used by Link mains but I think it can utilized more and used in ways that could elevate Link's current viability.
