OK, in my opinion, the 1433 is basically non-portable and 220 is better. 220 is using both “legs” of the power supply, each carrying 110VAC but “swinging” opposite each other on the sine-wave. So effectively, you’re using only half the current to start and run your motor, and you have more current available when “loading” the machine. I think you get the drift.

Oh, standard house voltages here in the USA typically run at 117VAC, so technically it’s 234VAC available at the main. If you have a meter you can measure this yourself. If you don’t have any idea, then please consult an electrician. 220VAC will “nail” you to the wall. Oh, one other thing…My wife’s vacuum runs at 12 amps…these saws draw 7.5 and 10 amps…that’s pretty efficient.
