DVD-RW DVD+RW or DVD-RAM for LG GSA-E6OL

I’ve never used recordable DVD on a PC before the last week, my new LG GSA-E6OL supports all these formats. I bought some DVD+R disks for permanent data archiving, some web commentary saying the + is a little faster and more reliable. I’m stuck on whether there are any advantages to one of the three formats for rewritable DVDs. I found good prices on Fuji DVD+RW. with DVD-RAM costing twice as much. I read that DVD-RAM can be rewritten 100,000 times, but also that it’s obsolete and replaced by RW (?) Expert help appreciated.
