I used both. I agree that a dirty diaper is a dirty diaper! I used the disposable liners and would dump the solids into the toilet. Newborn BM (sorry if TMI) is not solid, just FYI.
I both lined dried and dryer dried my cloth diapers. I had 3 different brands and some could not be dryer-dried. But I didn't have enough to line-dry all of them (took too long). I needed to have at least 6-10 for a day, sometimes 12 for one day's worth, especially newborns.
The fleece and hemp liners for the pocket diapers are a wonderful thing to increase absorbency over using a cloth diaper insert. Hemp is resistent to odor as well so a great thing (but more expensive--I got some as gifts).
I used cloth exclusively for 3 months and then went back to work part-time. My daycare only would use disposables. So then I used cloth at home until my boys outgrew what I had (about 6-8 months). I should have purchased larger sizes but I didn't at the time. Hindsight!
The cost of washing/drying the diapers was negligible. A tiny bit more work but I do laundry anyway so a load of diapers wasn't a big deal.
I enjoyed using the cloth diapers and enjoyed doing the reserach on them. Good luck!
