Drop bars with STI. 3T bars have a nice flat top behind the brifters. The thing with drops and brifters is that there are hand positions associated with the hoods that do not involve holding a round bar. Hence better hand comfort. I don't know of a brake lever on the market that provides the same comfort and hand positions provided by a modern brifter. Close, but not the same.

Bullhorns and aerobars or drop bars with clipons are good options, too, IMO.
