TI Jazz Rounds vs DR Sunbeams for 5 string fretless?

[timmerel]

Which do you prefer, and why?

My fave fretless tone is Mick Karn from his Japan Tin Drum album for reference.

Anyone?

TI jazz rounds are my all time favorite strings. Warm and expressive with plenty of edge if you want it. Supple and slinky and nothing else feels like them. Sunbeams are the closest similar strings but they're not the same. Nothing else feels or sounds like the TIs. And they last forever. Worth every penny.

What's the difference between them on a fretless?
