I have put 5 scopes, from 1X20 to 2-7X32, on my 357 shorty in the last month. Like you, I started not really knowing what I was looking for.
What I have found is that 1 or 2.5X is about perfect. In the end, I prefer the 2.5X for most shooting, but chose to dress it permanently with the 1X20. It is a kids deer rifle and I do not want to encourage stretching the 357s effective range.
By far, the least favorite scope tried was a TruGlo 2X red dot. For all the reasons that PowPow listed, and also because it sat way to high above the bore.
