Current equivelent model now is the Panasonic Lumix FZ-80. There don't seem to be any FZ-70 advertised anymore. The FZ-80 has the advantage of Wi-Fi connectivity.

Canon and Nikon used to, and probably still do, make very comparable models. with slightly less zoom range.
Edit. That Nikon Coolpix P900 is exactly what I mean and has about the same long zoom. I am sure it would be just as high quality, perhaps just a little bit more money, but check and compare the features to see which suits your needs best.
I had a stint doing serious motor sports photography for Magazines in my young days and had lots of SLR's and long lenses.
This superzoom makes those, and most, if not all modern SLR's, look and perform clumsy. The only thing you really gain from an SLR is a much larger image sensor and possibly better lenses that have a much smaller zoom range, fill a suitcase and cost a fortune. But the extra quality of the image is not really an advantage for normal posting to, and viewing on compluter screens. If I was still trying to get published in magazines (do they still even exist?

) the possible extra quality of the SLR image may mean a lot more.
The other big advantage to me is that the superzoom very effectively replaces a HD video camera. Some SLR's do to, but at far higher price.
