Yes I have actually tested
every single different set and gauge of Worth for 4 string (not the 5, 6, or 8 string sets since I have no instruments like that)
Worth makes both Brown, and also CLEAR fluorocarbon strings, and 16 different varieties (sets) of each color, see here:
http://worthc.to/english/w_strings.html
I have found that stringsbymail.com carries almost all of them, if not all of them.
I've tried both brands (also the Martin M600 soprano/concert sets as well as the M630 baritone set), liked them for different reasons on different ukes. However, I find that with Martin M620 Tenor strings, the C string, or 3rd string, tends to go floppy and sound flub-dub-tubby after the strings have settled for about 3 weeks...
Martin strings across the board seem to settle to tuning and tension after about 10 days if your play EVERY DAY for at least 20 mins, and then, once relaxed, they have a lower tension than the first few days when you put them on.
The Worth
Brown Tenor set, both low G (BT-LG) and high G (BT) seem to have not only a bit more tension, but a more BALANCED tension across the strings.
I find that most clear fluorocarbon strings have a bright (sometimes harsh, depending on the instrument) jangly tone, whereas the Worth BROWN strings have a slightly warmer tone, slightly sweeter (dulcet) tone, whereby the difference is most evident if you are playing with fingernails or a plastic pick, if you are playing with soft fingerpads, you may not hear the difference....
The Worth Browns also seem to create pleasing overtones that are missed with most clear fluorocarbon strings due to the scratchy treble that is more dominant to the ear.
But all of the above perception can be either mitigated or enhanced based upon your playing technique.
Which strings have more texture? If anything the Worth strings seem to be smoother to me than most others, with the Browns being the smoothest (almost silky even), rivaled only by Fremont Blacklines...but the Martin M620 tenor strings are smooth too...
