CDR is stronger in lane, mpen is stronger in teamfights (where ability spam is relatively low compared to lane phase).

Personally I prefer CDR boots since I'm not really getting CDR anywhere else (I usually leave my blue for someone else and blue elixirs only come into play late game for me). But if you like taking blue buff (and/or your jungle gives it to you, or you have other sources of CDR) mpen boots are obviously superior. It really depends on how you play and where you usually get your stats from, CDR has many "temporary" sources like blue buff and blue elixir while mpen is usually only gotten in the form of boots and void staff (excluding masteries and runes).
