I will gladly sacrifice a little speed if it gains me stability.
A good grip on a heavy riser with arrows in the 11-12 grain range shoot the most consistent for me. I think this combo. helps to forgive my form breaks some.

Stability, shootability, accuracy, all have way more to do with the quality of build, fit to you, tuning of the bow, arrow, ect than speed. A slow bow is not inherently more or less accurate than a fast bow and vice versa. So the answer is no.

Just a thought...I have no idea where the line gets crossed, but I know on the "other" side of the sport things like stabilizers, drop-away rests, mechanical heads, release aids, etc. were developed at least in part because the faster they get, the more finicky they are to shoot.

When I think of "more critical" I think "less forgiving".  

In that context I would say faster bows are more critical for most people. Not all but definitely most. It's simply a matter of physics and trade offs.

LBR has an interesting point and analogy I agree with

Often a " fast " bow is shorter , and and i think that a longer bow is more forgiving generaly
speaking .
