One thing I do not understand about disposables is this : they manufacture long-hours use ones that cost a lot.  But if you think carefully, surely you won't want your precious baby to be wrapped in his own waste for even an hour.  One salesperson actually told me her brands' mid-range diaper (i.e. not long-wear) is for up to 5 hours use, which means the long-wear one is longer.  So assuming I use disposables and I do not want to buy the long-wear ones because I do not want my baby to sit in his own pee (not even for a minutes, if I can help it!), I should go for the not-so-long-wear ones.  In other words, the concept of long-wear diapers is complete uselessness.  But that means I have to keep changing anyway and how would that be different from using cloth, except that the disposables are more expensive.  Ok, they may be more convenient to use, but certainly does not make economic sense.

Even if you have decided to go for cloth diapering, you will have to consider the cost of different cloth diapering system.  Flats may be cheaper, but in terms of value for money, I will vote for prefolds.  AIOs, though convenient to use, tend to be more expensive.  Hence, the type of cloth diaper you use will also depend on your budget.

2. Ease of wearing
Using cloth diapers may involve a few more steps in wearing the diaper, depending on what type of diapers you use.  For flats, for instance, you will need to fold the diaper, place baby on folded flats, cover up, pin/wear a cover over it.  For AIOs, you place the soaker in the AIO, place baby over it and pin up.  Some AIOs do not even need you to insert a soaker as the soakers are sewn on.

What you end up buying depends on how easy you want it to be.  And most of the time, the easier it is to use, the more costly it is.  E.g. AIO would be the easiest  but one of the most expensive.

3. Ease of washing and drying
Most of the time, washing is not a problem, as long as you have a fully automatic washing machine.  I don't find washing diapers troublesome at all.  The mindset that cloth diapers are troublesome because of the washing came from the time laundry was done by hand.  Situation is certainly very different now.
 
As for drying, most Singaporeans are still hanging their clothes out to dry and our weather is generally very favourable for cloth diapering.  On the other hand, more and more people are using dryers and this makes drying even easier.  The downside is that dryers consume a lot of electricity, so be prepared for a big utility bill.

Now, among the different types of diapers, the more complicated the construction, the harder it is to dry; the thicker it is, the harder to dry.  Hence, AIO is one of the hardest to dry in general.  Flats dry almost immediately in good weather.
