ditchfield,

For some rather thorough product descriptions and many threads giving pros & cons of the small lights that you mentioned, as well as some others that you may not have considered (ARC AA) , please go to
www.candlepowerforums.com
and use their search function with your flashlight names as search info.

Also, check out the ARC flashlight forum thread (from the CPF homepage scroll about halfway down. They have links to quite a few of the flashlight company as well.

FYI ARC Flashlights is currently having a nice sale on some of their products, you can pick up their link via CPF.

FWIW
I've purchased several of the ARC products and have been very happy with their form factor, fit, finish & performance. They do cost a bit more than some other products, however one needs to consider just what the differences are between the products being considered. In general, I've been quite pleased with the ARC line and they STAND UP behind their product warranty/guarantee.

Disclaimers
I am not associated with ARC except as a very satisfied customer, and I post on the CPF Forums as Lighthouse.

HTH
