What determines what makes a 'better' shave? That's really the question.
I think that any of us could get a shave that's as close or closer than what we could get off an R41 if we did a 3-pass shave with a 5-blade cartridge razor. Hysteresis will almost certainly allow a closer shave than from a single-blade razor................especially if you do an ATG pass to finish up.
However, in my case that caused severe irritation and ingrowns.
So, I'd say that is not a good shave. The aim of shaving is to get a shave that is comfortable FIRST, and also close enough to be presentable through a workday (or into the night, if you're still at the nightclub stage). We all try and extend the time that our faces are smooth, but if we do that at the expense of comfort, it's a waste.
This is where I've been heading with my technique lately. A four-pass shave with ATG is virtually guaranteed to give me irritation regardless of what products I use. Lately, I've been doing a 2-pass shave (WTG, XTG) with minor touch-ups. It's faster, and it gives a very presentable shave with no irritation.
