But I don't think the 830 is anywhere near as good as the 3 above. Still dreaming of the Panasonic CM1 with its 1" sensor & total manual control (even with a control ring around the lens).

I had both the 1020 and the 930. Those are the two flagship models they had.

I think it will be significant. The main advantages of the larger sensor in the TZ100 are more dynamic range (the difference in the light intensity of the shadows & the highlights), more control over depth of field (the ability to blur the background while keeping the subject in focus), & better low light performance. This last one is the most important for concert photography.
Both cameras have slow (small aperture) lenses, which don't let a lot of light into the camera. The TZ90 is f/3.3-6.4, while the TZ100 is for/2.8-5.6 (lower is better, so the TZ100 had a slight advantage here). As a reference a fast f/1.4 lens will let in four times more light than an aperture of f/2.8, & sixteen times more light than an aperture of f/5.6!
For concerts the shutter speed must be reasonably fast, to freeze motion without blurring. But concerts are a low light environment. If you have a reasonably fast shutter speed & a slow lens you must bump up the camera's ISO (sensitivity). The problem with high ISO is that it creates noise.
An approximation of correct exposure of these cameras at a concert would be as follows (using an exposure value of 8, if you want to Google an exposure value chart);
At a shutter speed of 1/125s, when zoomed out (at aperture f/2.8), you would need an ISO of 400. This ISO is reasonably high for the small sensor TZ90, though still acceptable. The larger sensor TZ100 will still perform well at this ISO.
When zoomed in the aperture will close, admitting less light. At an aperture of f/5.6 the ISO required for correct exposure would be 1600! At this ISO the TZ90 will perform poorly, with a lot of noise. The TZ100 should be acceptable, though not brilliant.
You may choose to use a slower shutter speed, around 1/60s. This will create a little bit of blur, which maybe ok for photos, & is actually a good idea for videos. For photos at 1/60s, you'll need an ISO of 200 when zoomed in, & 800 when zoomed out. So these photos won't be quite as noisy as those above (with the faster shutter speeds).
I couldn't find any pics in the U2start gallery that Welsh_Edge linked, for either camera. The closest I could find is the Panasonic TZ60, which is quite similar to the TZ90, though a few years older (30x zoom & small 1/2.3” sensor).

Check the pictures in their original full sizes. Notice the background of these photos, they are very noisy! The larger sensor TZ100 will produce much less noise.
