I've owned and used the TZ7, TZ40 and (currently) the TZ70. All have served me well. Unfortunately, some reviewers have been less than satisfied with the TZ200, as in this case: Panasonic Lumix DC-ZS200/TZ200 Review: Digital Photography Review (dpreview.com)
I have it’s forbear the TZ100 which I am quite happy with, very good image quality and many features but viewfinder is too small. 250mm zoom is plenty for me. Not as ergonomically pleasing as my Canon G5x. If you can live without the longer zoom the TZ100 is a nice little package.
