I cannot speak for you obviously but coming from a person with around a dozen different Speedmasters I can honestly say that if I were forced to choose ONLY 1 modern Speedmaster for ALL occasions, it would have to be this EW 321.
If it were 2, then I would include the Moonshine.
If it were 3, then I would include the recent Snoopy 3.
If it were 4, then I would include the Silver Snoopy.
If 5, then most likely the Soyuz with meteorite dial.
If 6, possibly the Apollo 8.
Again, these are my picks for modern Speedmasters and for different reasons and purposes. I have taken the hype and price factor out when making these choices so based them on preference and how special I think they are.
Before this EW 321, the Moonshine was my favorite modern Speedmaster and probably still is but I would rank them 1A and 1B, not 1 and 2. π€·ββοΈπ€£π
I would choose the EW 321 over the Moonshine if forced since it is in SS and more wearable in most situations π
