no major difference in aging carboy or bottle. carboy is often convenient because it takes up less space so if you can spare tying up the carboy for a few months that's what i'd do... especially if there is still clarification to go.
if you are going to let it bulk age, be sure to follow instructions accordingly. usually this includes adding 1/4tsp k-meta/6 gallons.
keep your airlocks filled, a dry airlock will ruin your 6 gallons quite quickly.
keep the carboy topped up to within 2" of the bottom of the bung/stopper
a quick twist of the carboy for a few days in a row will sometimes release yeast and sediment clinging to the sides of the carboy.
dont be in a rush to bottle... bulk aging will allow more sediment to settle and more CO2 to naturally come out of suspension.
if you take a sample into a wine glass i'd be interested in seeing the color and clarity you have right now.
ultimately you want it to settle enough that it is bright and crystal clear, it may be tinted, but there should be no cloudiness or particulate floating around.
