With respect, you can't recommend something like the bespoke tailoring experience offered by a particular tailor if you haven't personally been a customer. Otherwise there is no integrity in your recommendation.
Rather than recommend something based on someone else's experience, you should confine yourself to broad statements like "I know someone who has used such and such" in the first instance, instead of "recommending" him and trying to bignote yourself.
Now to the crux of the matter. From what I have seen in the evidence posted openly by Phat Guido and others, P Johnson delivers the goods in terms of suits and jackets that fit well and flatter their wearers. E.g.
By contrast, your bespoke experience yeilded a result that looked like it barely (if at all) shades an average RTW suit. I'd link to your photos here for comparison but they have been taken down (which probably tells us all we need to know) from the original thread
You can bang on all you like about "the experience" of bespoke being superior to MTM, but when your bespoke "experience" is limited to one baggy suit from a second rate tailor, your opinion isn't worth a pinch of shit.
