I have never tried gDiapers but I am a cloth diapering Mama :) When I invested $ in cd'ing I did not know of gDiapers! What a great concept...flushable diapers!!!!
I bought all-in-one cloth diapers (a.k.a. AIO's) that have the absorbant inner & waterproof outer all in one diaper. The brand I bought was Kushies & they really held up great through 1 baby & I will use them again for my baby-to-be come July :) They have velco tabs & are just as convenient as disposables (when I am home). When I am done with a diaper, I just toss it in my Wahmies Diaper Pail Liner until I launder them. I launder my cd's in hot water with Fragrance-Free Organic Detergent by Shaklee. I use distilled White Vinegar inside a Downey ball & it softens the diapers (just as fabric softener would without depositing softener on the diaper, which affects the absorption). It's just a little extra laundry & well worth it IMO financially & environmentally speaking.
I have used Seventh Generation disposables for extended stays away from home & highly recommend them!
Good luck to you, your baby, & your "green" diapering. You'll find what works best for you in no time :)
