If this is a prelude to learning to fly, then perhaps budget is the first thing you should look at. Not to get the licence (though you need to do this as well) but to continue flying afterwards.
The differences/challenges are not the same. Arguably flying a helicopter is more difficult - but the long distance touring you can do with an aeroplane is more difficult than the (generally) short, local flights with a heli.
Fly safe, Sam.
