That Tempress Trojan looks practially identical to my 2016 ZX seat, fwiw.
I tried the Millinium B-100, it's comfortable but big, wider than most seats. Takes up a lot of room, esp on a narrower beam boat.
I stand most of the time, but also with a bad back on long days it's nice to take break/rest, and I use the smaller version of the Millinium Palma style - the Mossy Oak version. It's not as wide as the standard Palma - I think it's actually meant for the smaller duck boat crowd, tbh. But I like it. Drew Cook and Drew Benton both have it on thier Elite boats as well.
But for comfort, the B-100 is a winner if the size doesn't bother you.
