I use TI flats now, but more for the tone and feel, than concerns about wear (on ebony fingerboards). I don't happen to be going for a Jaco sound, but thought I'd add a few notes on wear.
Take a very close look at the strings - use a magnifying glass, a loupe, a good close up lens, or maybe even a 10x microscope. There is a huge difference in the surface finish from different manufacturers, and styles.
TI jazz rounds, and nickel Coco's (my previous favorite), tend to be quite smooth, and of course nickel is much softer than stainless. Some others looks like a chainsaw. (Alembics are actually quite smooth.)
There really is a lot of variation, so if you want to use rounds and are concerned about wear, then take a close look.
