Induction is fantastic for boiling water, so if I were to get my dream range it'd be a 36" with a convection electric oven and two induction burners at high wattage (3600W) and 4 gas hobs w/ at least one gas hob being a tri-ring style burner.
I think having 4 gas and 2 induction would be better. You can use the induction with a disc-bottom stock pot for making pasta or other things that require boiling large quantities of liquid. Induction is bar-none the fastest way to boil lots of water. Gas can be used for most everything else. Induction is really good with disc-bottom cookware generally since disc-bottom cookware tends to be very even and counter-acts the induction unevenness, but it also retains a lot of heat and doesn't run heat up the walls like typical clad cookware.
