This chapter is a brief summary of the panel discussion. The goal was to present the main differences concerning not only the instrumentation itself but also the language which is used by both community.

The summary does not appear as a standard panel discussion where several people interact because we have chosen to compare both techniques through three fundamental aspects:

• The expression of the interferometric equation
• The instrumental differences
• The atmospheric behaviour and the noise properties
