I'll go with the Fenix E05. Its got a better tint/beam, its brighter, and its smaller than the E01 (which is awesome too). I like how its simple and doesn't have multiple modes, I don't need a moonlight or super bright on my key chain. I think the floody 30 lumen beam is perfect for this type of light. The runtime isn't there but I use it as a key chain light, my EDC has the low-low/high lumens and runtimes. I don't care that the lens is plastic.
