I couldn't answer your poll because a .40 S&W and a 10mm are the same caliber.
However, if you meant which chambering do I like better, I guess I'll take the 10mm, since it is a somewhat unique chambering. It has power approaching the .41 magnum, but in a semi-auto platform. Something about a 16 shot .41 magnum makes me feel all warm inside.
The .40 S&W, on the other hand, is less useful to me than the .45 ACP which has been around for a hundred years, has a pleasant recoil, and outperforms the high pressure .40's, with less wear and tear on the gun and the shooter.

I voted for 10mm. The 10mm is one seriously awesome round! It does cost more to shoot unless you are a handloader, but the capabilities are much greater than the .40
A lot of this depends on what you want it for ? I would be very nervous about shoot a 10mm. in my home if I have a family.
Where is that round going to stop after it goes through the BG because it's not going to stop in the bad guy.
A 40 , frag hollow point ,ok , I feel a little better.
The more important concern to me is actually being able to hit the target, under extreme stress, and having the discipline not to shoot in a direction where there are innocents in the background, with whatever round you intend to fire. That is a very tall order, by itself, if your life is being threatened.
If you look at ballistics charts, with all kinds(manufacturers) of ammo, between the .40 and the 10mm.....using 180 gr. and 200 gr. respectfully..the only major difference is ft. lbs. of force, and cost.
Like I said...........
.40 on steroids = 10mm
10mm is my preferred carry round.
A .40 is to a 10mm,what a .38 special is to a .357 Magnum.
Price and availability of the 10mm is my only concern. As far as over penetration, for what is worth, for defense purposes I use hollow point ammo.
