I've used reusable a for all three kids - from 10 months with my first, and from birth for the other two.
I'm not a nappy evangelist, and use disposables at night, and sometimes during the day if I just can't be bothered
If I'm honest, with my girls in particular, I use them because they look cute (shallow, I know). I use Itti Bitti and Blueberries, which are cute and fluffy (from 6 months up, but can be used from birth).
From experience, using from newborn is easier than it sounds, and if you use a good nappy with a good cover over top you get a lot less of the dreaded up the back poo explosions! My personal preference is to use one system up to weaning, then another type afterwards, but opinions vary.
You definitely save money over time, especially if you use the nappies again - my 20 month old is in the nappies her older sister wore. There's also a healthy resale market, so you can get some money back once you're done. Children in real nappies often potty train a little bit earlier too, so you can potentially get the nappy stage over quicker.
I wash every 2nd day, and don't notice any smell from the nappy bucket. We don't have a drier, so I either dry on the line outside, or on airers/radiators inside.
To try them out, buy 2nd hand - used nappies are more absorbent than new ones, and I often see complete systems for sale on here for less than £50.
Good luck x
