Honestly, the main reason I like my GI lensatic compass is the inductive damping - no liquid to leak/form bubbles/get sluggish in the cold.

The main drawback is it is not convenient to use it as a protractor to transfer an azmuth directly to or from a map.

The reason for a lensatic compass is to be able to accurately sight a bearing/heading. The best you can do with a baseplate compass is hold it against your chest and rotate your body until the needle is "caged" and then look up straight ahead.

Although that's probably good enough for most uses.
