While I’m sure a lot of people will appreciate the 2020 specs, I personally also love the previous model. The main reason is the phase III locking tuners, which I prefer to the vintage style. The second reason is that, while TCI tuning is nice, I almost always use full humbuckers on the 594. If I want a single coil sound I switch to a Danocaster or FCS strat.
There are times that I'll use the split for dynamics rather than chasing single coil tone.
Having said that the 5909 in my McCarty is fairly convincing in single coil mode.
