Burn with nero or DVD decrypter?



I am a newbe here…can u help me?

what is the best to write a DVD,to use nero with DVD shrink, or use DVD decripter(with DVD shrink) and make an ISO image.

so far I did 30 backups with IFO from DVD decripter , then dvd schrink, and used nero to burn.works perfectly

I dont see any difference with IFO or ISO…
