DVD-R or DVD+R Difference

So I have just finished ripping a bunch of old VHS tapes to the PC and now I want to burn them to DVD but I am not sure which DVD type I should be burning them to for best results.

My DVD burner can handle both formats but could someone please tell me which DVD type would be better for home video viewing?

DVD-R or DVD+R!

What is the difference, I can't find an easy answer.

Thank you :D
