It's interesting that Arnold basically inspired Chuck to put up his 3el KLM 75M Yagi. Chuck took a trip to LI and Arnold picked him up in a limo and whisked him off to his QTH. Arnold had up one of those driven cell, 4el KLM jobs. The boom snapped during an ice storm the SAME week that Chuck had his new 3el operational. So they never really had a chance to do a 1:1 comparison. Afterwards Arnold had up a single 75M NE loop on his tall tower and a second one at right angles to SE.
Over years of pecker matching, I found my best 75M Yagi system (7 el wire Yagi at 130') was about par with Chuck into Eu and we were both about 5db stronger than Arnold. This was due to Arnold's missing Yagi, I'm sure. When you have a good loacation, run a Yagi and competitive power, there's not much more you can do - and the signals get very close to one another. The only variance becomes cornditions, audio and of course, reputation. At the time, the call "WA1EKV" and "W2HCW" were both worth a few db...
Being the new kid on the block (1986) I had rough sledding amongst these tall ships despite doing everything I could to compete.
