Perhaps you should ask yourself where do you intend to buy most of
your appliances and what type of electrical system are you installing?
Although there are exceptions throughout the world, most 50 Hz systems
are 240V and these systems are widely used in Europe, Africa, Asia
(Japan is the exception at 100V. Nominal, about 1/2 50Hz, the other
half has 60 Hz).
The 120/240 60Hz system is mostly used in the US, Canada, Mexico.
Some appliances (computers, electronics, mostly) are designed with
universal power systems and can be used on any system, regardless of
voltage or frequency.
However, there are many appliances that may give you performance
problems or, in the worst cast, start smoking if you use them at the
wrong frequency or voltage.
One of the original downsides of 50 Hz was that low wattage
incandescent bulbs might have a noticable flicker. Some say that
this is no longer a problem because of CF lamps.
AC Motors may run at different speeds when given different
frequencies. This can affect things like clocks, timers on washing

The difference between 50 and 60 Hz is not very great and the two
systems exist for historical reasons. Higher frequency means lighter
motors & transformers (less iron) for a given power rating.
Synchronous motors run at different speeds. 60 Hz motor may overheat
on 50 Hz. Induced hum in audio equipment, phone lines, etc will be
different pitch. Aircraft and some ships use 400 Hz for lighter motors
My 50 Hz filament lamps (UK) do not flicker that I can see, except
when filament is about to fail.
Swiss German Austrian Scandinavian railways use 15 kV 16.66 Hz (16 2/3
Hz) (Norway Sweden) or 16.7 Hz (Ger Sw Aus) power for traction. Bulbs
in signals etc run on power frequency flicker visibly. Some US
railways use 11 kV 25 Hz.
Consult good electrical engineering textbooks for further information.
There are no big advantages or disadvantages between 50Hz and 60Hz, just
differences and some incompatibility issues.
What has already been written is true, apart from the voltage it is mainly
synchronous motors and maybe some transformers where frequency could be an
issue. Some of the older turntables for hi-fi systems, clocks and timers use
synchronous motors so these may not be compatible. I think that some devices
may use the mains frequency to derive a "clock" frequency, perhaps some
mains operated digital clocks may have used this though crystals aren't that
expensive. Power factor correction for some devices may need to be changed
for the different frequency.
One lesser known device where frequency is important is the ferroresonant
transformer. While this isn't a well known device, I believe it is commonly
used as the transformer in microwave ovens and will be tuned to a particular
mains frequency. Using such a frequency sensitive component would not just
be a problem if used in a different continent, but could also be problematic
if powered from a petrol generator where the frequency may not have good
regulation. A normal mains supply has a well regulated frequency.
If it answers your question, to adopt a higher frequency the effect would be
that some appliances would no longer be useable. By "useable" I mean that
for example, some clocks would work though they would not keep good time.
There would be many devices where a different frequency would cause no
noticeable difference. Mostly, it is voltage that causes incompatibility and
If you were thinking of moving somewhere where there is a different mains
frequency or voltage, it would be best to work out which items you want to
take with you and asking a qualified electrician whether the appliance would
work. Normally a mains operated appliance will have the operating range of
voltages and frequencies printed on it.
I hope this helps
