Well, your bottom two seem to be more focused on reflectivity, whereas the top two are more "transitional weather" vests with reflective piping as an added feature.
Which is more important to you is up to you.
That said...I have an older version of the PI vest, and one big stink I have with it is that it has/had no pocket. I see this version does, and that's nice to see. Otherwise, I like my PI vest fine and find a vest handy for those in-between sort of days.
