My EDC has been a 940 for quite a while now. Out of the box, it is easier on pockets, but I suspect G-10 could be smoothed under/around the curved portion of the clip to make it just as clothing friendly without impacting it's "gripability".
Whether the aluminum shows wear or not depends on how you use/care for it. Mine has only a single ding. I don't take any special precautions since this is my EDC, but I don't carry other metal (like keys) in the same pocket. Other than that single ding, the handles show no signs of wear anywhere, not even the edges. In fact, except for the typical wear on the clip (black finish wears on the edges on every BM I've owned), several sharpenings, and the single ding, this knife looks factory new. This is after daily carry for at least a year or more and a lot of handling/use. I agree that checkered G-10 provides a better grip, but the aluminum does have a slight "grain" to it and, with the design of the knife, gives a much better grip than I would have expected from aluminum.
Something to consider is whether you will be using it with heavy gloves on. If so, the checkering on G-10 might help. If you're like me, though, I use my first finger in the curved part of the clip to pull the knife out of my pocket while my thumb rides down the knife in preparation of opening it. Even with heavy gloves, this technique works.
