Edit: All disclosures are on my respective reviews on the blog but wanted to make it clear that simplehuman has sent me the Sensor Mirror Pro and the Wide, Sephora sent me the 5" Original, and I purchased the original 8" Sensor Mirror prior to receiving any sample products.

What is the driving force behind your desire for a simplehuman mirror vs. something like a Conair or Ott-lite?

Here are some cons: the latest and greatest 8" Sensor Mirror Pro doesn't have the same height adjustments as the original, but the original 8" Sensor Mirror only has one level of magnification and the motion sensor is overly sensitive/not adjustable so it does go on and off easily (that was my biggest issue with the originals). If you are getting any of the round mirrors, they are all magnifying, so if you want to see a normal view of yourself, you'll need an additional mirror. The Wide mirror doesn't have any magnification, has a ridiculously large footprint, and the adjustable side panels never felt as sleek/well-made compared to most simplehuman products to me. If you don't have an Apple or Android phone, you will not be able to take advantage of the newer features on the Pro models (they are app-based last I looked).

If you are getting the 8" version, the latest model ("Sensor Mirror Pro"), which is more expensive than the original one, is improved over the original in a lot of ways. There were real cons to the first one that they addressed in the latest model (though you have to be able to use their mobile app!) - e.g. being able to change how short/long it stays on, it has a detachable (magnetic) mini mirror that has additional magnification (it sits on the center of the mirror when you want to use it and when not, it's on the back), and adjust the brightness/tone of the light.

The quality of the light and mirror are great across all models I've tried (Pro, 8" Original, 5" Original, Pro Wide-View), and I used the original 8" nearly daily and never had an issue with it holding a charge/recharging nor has the light dimmed or gone out. I also have the smaller one, which I probably use more often (not daily but for 2-3 hours at a time with a lot of on and off), and it is also still going strong. (I believe it's been two years.) It uses LED lights, and the press relesae listed they're supposed to last for over 40,000 hours (works out to be 55 years of two hours of daily usage or over 100 years of one hour, daily usage).

I'm not a fan of the Pro Wide-View (unless for some reason you can't mount a mirror on a wall, I just find it lacking in functionality for as much space on a counter/vanity it takes up). I think the 5" is only useful if you NEED 10X for the majority of your makeup. I use mine primarily for applying lip products for swatches or for plucking stray brow hairs. Even for eyeshadow, it is useful, but I prefer 5x magnification to be able to blend better but still have a better picture of what everything looks like normally.
