xenoxion,
It really depends on the type of circuit and personal preference. If this is your first attempt at home made circuits, you don't want anything too complex!
The three boards you linked to are all good and are commonly used, but for different circuits. If your circuit is going to contain a lot of logic or ICs, then you want the prototyping board. This is because the tracks are laid out so that you can have power rails and busses, and the distance between the copper cladding is just right for ICs. But there is still room for discrete components.
If its mainly discrete components (resistors, capacitors etc.) then you want strip board. This is because you have a very large wide area in which to work, and if you only have one or two ICs, then it is easier to drill out the strips in the middle of them, than it is for 20 ICs (very time consuming!)
However, I wouldn't use the experimenter's board. This is because all you effectively have are solder points, you would need to solder in your own wire links to make the circuit. This would get extremely messy and complex, no matter how careful you were. Plus, you'd have a hard time doing any debugging!
Personally, I'd use the strip board, unless I have more than about 7 ICs, then I'd go for the prototype board. But if I have a lot of support components for the ICs then strip board is again better!
I hope this was of some help to you.
