Not a brewmaster - don't even play one on TV...but:
BC - PRO:crush your own (save $0.10 a pound if you buy a batch or 2 at a time, meh, but saves a buttload if you go in on *bulk grain buys!), may easily increase efficiency, grain is crushed fresh (vs. ordering from online - see *bulk grain buys - this also leads to spontaneous brewdays when hops and yeast in bulk are added to the storeroom )... CON: Hmmm...
Kegging - PRO: Fill one, not 53. Won't necessarily break if you drop it. Coolness factor of serving from a tap. Can carb without adding additional ingredients. Stores well - doesn't necessarily break if knocked over, either. CON: Beer must evaporate thru stainless steel because it sure doesn't last as long as bottled beer. Running out of CO2 on Saturday eve. really sucks. If you forget to label the keg you have to taste it to know what's in it. Wait - that might need to be listed under PRO...
and +1 to eschatz 'go for the keg' advice - I kegged before I got my BC
