After many grueling attempts and banging my head against the wall (thankfully less of the latter than the former), I finally beat Master Core on 9.0 using one of my Gunner Miis (mostly Attack based with a little Defense). Good lord, it felt so satisfying to do this!
Now some have asked me if fighting Master Core on 9.0 is harder or the equivalent of doing Boss Battles on Intense from Brawl. Let's compare the two, then I'll give my opinion on which is tougher.
Brawl Boss Battles on Intense difficulty has you fighting 10 bosses in a row, including all the major bosses from Subspace Emissary as well as Master/Crazy Hand, shuffled in a random order with Tabuu being saved for last always. Like All-Star mode, the player gets a rest between fights with three Heart Containers to bring their damage back to 0% should they require to. Having played Brawl pretty extensively in the day, I can definitely attest to the fact that this mode on Intense can be murder to your mind and fingers if you're not prepared for it. Certain bosses stand out from the others being hard (I'm looking at you, Duon), but with enough practice and quick reflexes, a majority of the bosses can be fought with little consequence.
Moving on, let's take a look at Master Core on 9.0. Unlike Boss Battles, this is done on the game's Classic mode, so the main challenge is actually GETTING to Master Core by defeating all the prior fighters before him. See, as we all know, if you lose both of your stock in a battle in Classic, you get a game over and the difficulty is turned down half a notch. That there is the major difference between this and Boss Battles. You have to do it all in one go and if you lose any fight beforehand or with the Core itself, you have to start over. As for fighting the Core itself, like many of the bosses in Brawl, practice, reflexes, and above all patience is a good thing to have when fighting all five parts to this fight (The Hands, Master Giant, Master Beast, Master Edges, and Master Shadow). I think among all of the forms, Master Edges is probably the one you have to be most careful around. The tells of his attacks can be quick and painful if you don't watch carefully. Master Shadow is probably the next hardest, because you're basically fighting a slightly stronger Level 9 CPU . Master Beast can be a pain, but his attacks all have tells that, while fast at times, can be easy to dodge. Master Giant...well, surprisingly was the one I had the least trouble with. All of his attacks can be very easily dodged sans the "Table Flip" attack.
Overall, which do I believe is more difficult? To be fair, each has it's own difficulty curve. Boss Battles is how well can you fight 10 foes with HP bars with limited recovery. Master Core 9.0 is a testament of endurance to make sure you make the least number of mistakes or be doomed to start from the beginning again. I'd probably still say Master Core has the edge in difficulty in that regard, but everyone has their own thoughts on this matter.
And with those paragraphs done, I'll leave others to discuss about this. *collapses from exhaustion*
