If you could have 220V for your tank, would you?

That's a pretty broad statement and although it may be true for some components, I wouldn't count on it. Just had a quick look at one of my AquaClear powerheads and the manufacturers label states AC 120V 60Hz, not 50-60Hz. Yes things designed for 50Hz may function at 60Hz, but not optimally and in some cases not at all. If you were to hook up a motor driven timer designed for 50 Hz to a 60 Hz supply, it would run fast. Most AC motors will run at a different speed depending on the frequency of the supplied voltage. Yes, there are automatic voltage sensing devices in most components today that allow you to plug into any supply from 110 to over 300 volts, but I have yet to see a component that automatically senses and changes frequency. Many use a transformer/power supply to convert the AC voltage to DC and yes, for those frequency is a non issue. By all means use the 220V, just trying to caution folks that they should confirm any "Euro product" they wish to run on 220V states on the label that it is indeed compatible with 60Hz.
