I think it depends which ...
I tend to find coated blades give me an irritable shave - that's platinum; definitely, chromium, often; titanium, also. Some SuperMax are simple, straight-up stainless, like the Vidyut/SuperMax in the burgundy packaging or the V(idyut)/SuperMax in the blue packaging. Those two, to me, have given very good shaves with both a face feel and regrowth as good as any stainless blades, all without the initial fierceness of some (Gillette, largely) stainless blades.
What I have also found is that there is a tremendous variation across the range, a range which is phenomenally confusing given there are ranges that span across brand names and across epochs. What I do know is that the new-style blades, the ones in the zappy packing with buzzword slogans like "Feel the power of Titanium" and "Now with new sputtered technology" are a significant step up from the older blades, or at least the blades that I believe are older. There are Super Platinum coated blades in those lines that I can tolerate well, where their older counterparts I cannot.
There are a couple of real gems! The Rise Stainless and the (discontinued) SuperMax Super Platinum, to me, are truly excellent. The rest, I could take or leave, but would be happy for the occasional shave with any of them ... with the exception of the old SuperMax Bue Diamond Titanium and the current market SuperMax Blue Diamond Platinum, neither of which I like at all (now).
I probably still have another two or three weeks of SuperMax blades to run through, and even then have not caught all of them ...
At that point, I will try to make sense of all that I've tried and write-up what I think. It'll be more about how I think they fit together - which epoch I think they belong to, which markets and which I think are the same as each other. While I will give my marks out of 10 and point to which I think are the better ones, it is a YMMV thing.
I don't know which you've tried, but these are ones I'd happily recommend:
9/10
9/10
8.5/10
8/10
7/10 for me is a good, honest, workable shave.
8/10 is "good" but still not ones I'd want to re-buy.
9/10 we're up to "very good" and blades I would re-buy.
10/10 is my "go to" blades that work for me any time, anywhere, any razor ...
For points of reference from the Gillette brand:
9/10 Gillette Super Thin (Thai)
8.5/10 Gillette Platinum
8/10 Gillette 7 O'Clock PermaSharp (Indian)
8/10 Gillette 7 O'Clock Sharp Edge (Yellow)
7/10 Gillette 7 O'Clock (Green)
7/10 Gillette London Bridge
... so, it rather depends what you've tried.
Oh, I should say I've been running these through the Muhle Rocca and the RazoRock German Slant, two razors which I'd say were not quite polar opposite but very different to each other.
