Kegs versus bottling. my 2 cents....
With Kegging, you will need more equipment. equipment - keg, co2 canister, co2 (i have a 20# tank, 32 dollars to fill, will last a few years, depended on how you use it, recurring expense)hoses, clamps, regulator, a designated cooling device (i.e.... kegerator, keezer), kegs get heavy when full, if your line leaks, you loose all your beer(one of my picnic taps dropped, and opened up - 4 gals of beer down the drain), you forget how many pints you have had ( especially when you do top offs)
With bottles it is - bottles, caps (recurring expense), bottle capper, bottling bucket, priming sugar( recurring expense). bottle bombs, 30-45 min to fill, cap, clean up.
upside to kegging - 5 min to fill the keg and in the fridge to carb,you can fill bottles and take them with you(and drink from the bottle with no worries)(you already bottles and caps and stuff, so why not use them). you can fill growlers, howlers. you can have carbed up beer faster ( i do set and forget, so still 2 weeks), clear beer. and so many more....
Upside to bottes- no dedicated cooling system (regular fridge would be fine for a 6 pack with out taking up to much space), easy to keep track of how many you have had. can store lots of different flavors without taking up to much space. (stackable cases).
i have 5 kegs, one is dedicated to Cider, I rotate 3 of them with beer, 1 is back up/ when I decide to brew more and rainy days,
