I strongly favor 110-74mm BCD drive over compact, because of the chain, cog, and ring wear issues mentioned earlier. Over the years, a compact drive will cost significantly more to operate. For those who care about how their gear ratios interleave from chainring to chainring, the larger cogs and rings provide better arithmetic selection than the smaller ones.
