are there one or two of these alternative methods that you have found particularly worthwhile to try in situations where Newton's method doesn't perform well? Thanks!

Thank you, unfortunately my (spoken and written) English really terrible, so you can enjoy them in Hungarian, if you check these:

Or these:

If you want to see something tricky, try this bisection in spreadsheet, but you can use the definition f(x) on 991CW:
