Quoted from PinMonk:The main difference is dual wound on JJP vs single wound on Stern. There might be a wire gauge difference, too. Just looking at them, Sterns seem to be a little thicker. That's for pulse, but in hold Stern is far and away the leader with their sub ms duty cycles to manage heat in hold. Given that Spooky made (another) new board and JJP just revised theirs, I have no idea why they didn't at least try to MATCH what Spike does for hold duty cycles. It makes a huge difference for heat management.
I just laugh at this because it’s just personal preference and some groups are out spoken.
Historically the dual winding Williams / JJP approach was considered so much better. But times change, opinions change.
I have zero problem with JJP flippers on DI or GNR.
I’m fine with modern Stern too.
