I can only really comment on the Shulk vs. Cloud comparison because I don't know as much about Marth and Meta Knight.So, I was watching one of Esam's streams earlier today and they all was talking about how they thought Cloud was the best Swordsman in the the Smash 4. Compared to all the other Swordsman Cloud has better frame date than them. However, I think either Marth, Meta Knight, and Shulk all have Cloud beat imo and this is coming from a Cloud main.
I don't think Shulk is a bad character I think Shulk is severely underatted and has tons of potential imo.
In terms of this Cloud vs. Shulk, "who's better" situation, frame data isn't the only distinguishing factor. Although, let me emphasize that this is a pretty significant difference between the two. Cloud's Limit is also a huge distinguishing factor between the two. The fact that he can kill so early in stocks fairly consistently (as opposed to Shulk needing to edgeguard or get hard Smash Arte smash attacks reads), is a pretty significant difference between Cloud and all of the other sword characters.
And, even though I understand that this argument isn't totally solid, I think it has to be noted how well Cloud's have been doing in bigger tournaments recently. Especially at Shots Fired 2. The fact that Shulk and many of the other swordsmen don't have that kind of representation will inevitably tilt the perception of Cloud towards being the best swordsman.
So, yeah, I would agree with Esam's stream and say that Cloud is the best swordsman, and I think Meta Knight and possibly (maybe not) Corrin are the only characters that can challenge his position. The only issue with Meta Knight currently, is that it seems like a lot of players have tended to stay at the ledge to avoid Meta Knight's brutal combos, which I think has hurt his effectiveness a little bit. Of course, as time goes on Meta Knights might adapt to that, and people may adapt to Clouds or something to that effect.
And yeah, Shulk could be really good. I just think it's really hard to be consistent with him at this point in time. I don't really think making an absolute opinion on him is fair at this time.
