I'm all about Res-C, so the B-10 LE is the hands down winner in my humble opinion. I have the Rodent 9, a couple B-10s, and had a BWM for a little while. I sold the BWM because I could not get used to the handle. I like the Rodent 9 handle much more, but Res-C is still king for choppers IMO.
The B-10 LE has several subjective advantages over the CG BWM: its blade is thicker yet lighter and more agile; it has a mean, razor sharp convex edge (at least mine do); it is Satin; it has Res-C handles, which offer more comfort and lighten the blade; it has a choilless option; and I'm sure there are other things I'm just not thinking of.
The B-10 LE is more comparable to the BWM-LE in my opinion, the main difference being that the BWM-LE is Sabre ground, while the B-10 LE is full flat ground and of course the B-10 LE can be had for A LOT less than the BWM-LE. If it's heavy duty chopping your doing, the BWM-LE will get the job done faster due to its added weight. I've never owned a BWM-LE because I already know that the handles don't work for me, but a lot of people say it is one of the all time classics. I think the B-10 LE will have a similar status some day, especially for those of us that like Res-C. It is just so incredibly agile, well balanced, and attractive to boot. It'll never chop like an NMFBM or other beefier BMs, but in my experience is more versatile for someone like me who needs to carry my blade for long distances and wants to have it ready on my person for clearing a trail or making a shelter. If you're looking to keep your BOB as light as possible, which is generally a good idea since you may be forced to cover a lot of ground if ever you are in a situation that requires your BOB, the B-10 LE will give you that plus the aforementioned versatility and more.
The main reason I did not like the BWM handle is because my hand was not quite big enough for the swells so it was uncomfortable and not secure. My hands are not tiny, but they are certainly not paws either (I wear a Medium or Large glove depending on the brand.) Then there is the dreaded pinky rub. Like the poster above said, if you wear gloves or have particularly calloused hands, you won't have this problem.
As you can tell, I am biased towards Res-C when it comes to 9"-10" blades. As a matter of fact, I am thinking of trading my second B-10 LE for a B-11 and filming an epic Res-C chop-off between the Basic 10-LE, Basic 11, Dog Father, DF-LE, Satin Battle Rat, and Scrap Yard 9-11 (when it comes out.) I may throw my Rodent 9 and NMSFNO into the mix just for the fun of it.
If you're thinking of getting one of the three, you'll most likely be happy with whatever you get and if you're not, you can always sell it and get one of the others. In the end, the best option for you is whatever best fits your needs. You also may want to think about the B-11, Dog Father or wait a bit for the Scrap Yard 9-11. Best of luck!
