No configuration is more naturally stable than a tripod. However, three legs of less than infinite stiffness will be less stiff than four such legs. If the legs themselves are relatively stiff (heavy pipe legs of 1.25" or larger diameter are not going to flex measurably) the main focus shifts to how the legs are attached to the top. The attachment flanges may flex, the pipe/flange joint may flex, and if the top is made of wood there will be some flexing. If the flanges and joints are heavy and stiff, then how the flanges are screwed or bolted to the top becomes critical. My next build will approach the bolts through the top just like bedding an action into a wood stock - with steel pillars and epoxy - and backing plates.
