Politics without political parties functioning in a country will be the best.
When contesting for election The only people that are qualified to run are those forwarded by a political party as there candidate there by making it hard for the people's choice to run.
When a political party is functioning in a country and one among which is on power any other person that those not belong to there political party will be seen as an opposition, that is why you see position being given to people that are not qualified for such position all because they are in the same political party there by causing damage to countries economy.
Political parties often have one common ideology, goals, aims and objectives which every of its members are expected to abide by and work towards. This means individual ideologies does not count. In a normal society free of corruption (which is kind of impossible anyway), having Political parties with good ideologies is just what the people need. An elected leader with a selfish agenda might not be able to actualize his aims because there are other political members available correcting his every moves.
But, the statements above are just like a mirage, they don't happen in real sense as every politician wants a share of the national cake too. There is also no guarantee that if there are no political parties and qualified candidates are voted base on the people's choice, things will be fine. Such a system is capable of making the elected leader too powerful. Remember the words of Lord Acton
power tends to corrupt and absolute power corrupts absolutely
