I also, ‘kind of agree.’
On the first shave I find the Reds smoother and more comfortable. However, the Blues ‘smooth out’ after a few shaves, then remain very comfortable for more shaves than the Reds.
In the end, I like both!!
I suspect that all depends upon the toughness of your beard. I rarely try pushing blades beyond 4 shaves because most start to feel either dull or harsh by that point.
