lol be warned, your addiction could get very pricey!!!
We had the flat type cloth nappies given to us with DD1 and used them for both girls until they fitted into medium sized MCNs
we werent sure how long smalls would last and given the outlay for med and large, thought it was the best option for us.
but to answer ur question yes they are better. you dnt need to change them as often as a terry flat because they matierials are much more absorbant, u dont need to fiddle with covers/snibs ect and well, theyre just better to look at too!!

Nappy bucet wise, we have an elmo one from target, doesnt necessarily seal tight but we dont have a smell issue with it at all, stays in the laundry.

Disposables- we never need them...ever! lol once u get the hang of MCNing it really doesnt cross ur minid to take disposables out with u, just take a few MCN's and wetbag! too easy.
But if u still feel like u need to buy some (which by the time u get around to using them ur bub will probably have out grown them!) i always found huggies to be the best.

Have fun!!
