Hey I don't know. I would think the 3" Magnum has better range.

which round is a better round and why
That is entirely subjective.
For me a 2 3/4" (12 gauge) is a better round. It kills deer and breaks clay as well as I could want.
For you the 3" (20 gauge) is needed for your gun to run. That in it self makes it a better round, for you, in that gun.
If you want to know more, get off of this gun forum and google '20 gauge slug ballistics' Buy some ammo and shoot it. DRAW YOUR OWN CONCLUSIONS!!! Then come back, as a new member of the elite keyboard commando opinion squad, and tell us what the better shell is.
Would you explain the "poorer ballistics" part?
Same powder load, heavier slug = less velocity and faster drop. Therefore, poorer ballistics.
I need to correct myself about the post I just made for ballistics. I just found some slugs (Federal) that uses the same size slug for both 3" as 2 3/4" with the 3" having more powder. If that is what you are using, then yes the 3" would have the better ballistics.
I was thinking about the case where all the extra 1/4" was taken up with a larger sized slug without increasing the powder load.

Fair enough, but consider this:
With two slugs of the same design (in this case, I assume, Foster) and different weights, the Heavy Slug will have a higher SD and BC.It will lose velocity at a slower rate than the Light Slug. Depending on Weights and Muzzle Velocities, the heavier slug will probably give up a bit in velocity and drop at 50 yards - but the heavier slug will almost certainly have the edge in FPE and Momentum - and better Terminal Ballistic performance. At greater distances, the Light Slug's advantage in External Ballistic performance diminishes, but the Heavy Slug's figures remain considerably better than the Light Slug's at the business end.
That's not to say I'd go with a 3" Slug load - I wouldn't. Either will do the job at normal shotgun range and, as you mention, the 2 3/4" Slug load usually has less recoil.
