I've got two aluminum and one carbon steer tubes to chop off but would like to purchase only one tool if possible. Will one of these tools work well with blades for carbon and aluminum tubes?

I'd get the SG-6 and use a steel blade for the carbon and alu. Just make sure a brand new blade is used on the carbon steerer.

i've cut both using a sg-6 with no issues at all. as said ^ either use a new blade or carbon specific blade when cutting carbon steerers

The SG 7.2 has two slots- one narrow one for a regular hacksaw blade and one wider one for the special carbon blade. It also fits things larger than a steerer, like integrated seat tubes.

I own the SG-6. When I need to cut carbon and use a thicker saw blade I simply insert washers under the removable plate to make the slot wider.
Also, don't get suckered into buying some "specialty cycling diamond blade" for cutting carbon. Buy a tungsten carbide hack saw blade for little to nothing. It's what pro shops use to cut carbon steer tubes. The cut is super smooth.
