I have em all except for the High Standard, so can’t speak on that one.
My 870’s and Winchester 1200/1300 Defenders get the most use, by far. You can’t go wrong with either.
If you want something new, it’s obviously gotta be the 870P. Don’t bother with the SXP.
When it comes to fixing on your own gun, if you are talking worst cast scenario, the Winchester 1200/1300s doesn’t require any special tools to replace key components like ejector and shell latches. The 870 requires a special tool for both.
There are still plenty of parts available for the 1200/1300 so don’t shy away from them just because of that. Smoothest action I have is a late 60’s Winchester 1200 Trench Gun. Like glass.
My advice: go out and buy which ever you think looks the coolest. Shoot it, and if you don’t like it, sell it and move on to the next. That’s what the EE is for
