Multibit vs Electrum - which is more mature and secure? I'm having a hard time finding objective reviews / comparisons of these two 'lite' clients. Can someone who tried them both give some comments?

Thanks
At the moment the Electrum client is more secure as the wallets are password protected. 

I am the lead developer on MultiBit and am working on wallet encryption but it will take me a few weeks yet. There are a number of changes to make.
