Everyone has their own style so I’m not being critical at all, but since you asked, here is why for me. First, I’m not 11 feet tall. Second, my hands spend 90% of the time on hats, ride and snare and my feet are 100% on the hihat and bass pedals. I orient everything else from there which means I want as little “stretch” from the baseline alignment as possible. To me how you have it here, to play a cadence across all your toms (in a fill, for example) you’re stretching well left of snare/bass (eg, “center”) for the high tom, back to center for mid tom, then right and behind you for floor tom…. Also having to go OVER your ride cymbal to get to the right side of the kit. I favor as compact a spread as possible with as few leaps between kit components as possible. I also play squarely behind my bass drum essentially facing at about 11 pm from there and all of my kit is no further than 90 degrees in either direction (eg it’s all in front of me). Side note: I do not play a gong, as rad as that would be. Again, every one plays differently and has different height and limb proportion, so take all that with a grain of salt. The aforementioned Purdy actually reversed his rack toms from the norm - larger left, lower right - as do a lot of drummers on their basic setups. Porcaro and Jimmy Chamberlain being two of my favorites. It is also not uncommon to have a rack/floor four piece base kit with an auxiliary high rack tom off to the left. Will Calhoun used to rock that setup.
