I don't know about the Micro-Light II, but the Freedom does not have the physical switch to accidentally toggle on, and if the button accidentally pressing is a problem, you can put it into demo mode where it is momentary on only.
One of the main alternatives in this ultra-compact category is the Nitecore Tube, which is brighter and USB rechargeable. I don't know how it does with accidental activation.
There are also a variety of compact round-cell lights to be had using lithium ion rechargeable 10180 batteries. The Fenix UC02 and Jetbeam Mini-1 are two examples. They are twisty-style lights. You tighten the head down to turn it on, and loosen it slightly to turn it off. As long as you loosen it more than a 1/4 turn, I find there to be low risk of accidental activation with twisties. These little 10180 powered lights usually a high and low mode.
The Xtar X-Craft is a similar (slight larger) button cell light but is USB rechargeable so less concerns with running down batteries.For many years I have used Photon Micro-Light II. I have grown tired of it turning itself on in my pockets and now I am searching for a replacement. I would prefer something in about the same size and weight.
Nitecore Tube has lockout. I have several.
There's not much to review with coin cell lights, simple 5mm on basic circuit with On/Off. FWIW, the one I have works and charges; although I did swap to a Yuji HiCRI.Xtar seems to have interesting keychain flashlights. Where are they sold? I can not find them anywhere and I can not find any reviews either.
I have been looking at Freedom as it got a real button and not just pressing the LED lead against the battery. Sadly, when looking at the reviews it looks like this button often breaks. Is this something that got fixed in later productions or is this still a problem?
I think I prefer flashlights with "normal" batteries and not the rechargeable ones. When reading reviews, it looks like those with rechargeable batteries are often breaking.

I have actually gone back to the Photon II for key chain use over the Freedom. The Freedom is a great light (I have not had any switch failures at all with mine) but it does turn on accidentally in pocket too often IME.I never had problems with the Photon II since the slide switch on mine seems to be stiff enough to prevent accidental activation. It may get a momentary activation on occasion but that isn't an issue for me as it does not put significant drain on the battery to run the batteries down like constant on does. Is it momentary activation that is plaguing you or is the slide switch getting turned on? If it is the slide switch a new Photon II with a stiffer switch might do the trick.
I am actually having problem with my slide switch, it is sliding too easily and the light is turned on before it is reaching the "locked" position.
