Welcome to the forums! 'Best Type' may be a bit hard to confirm, we have folks who spray in foam and folks who would never spray foam. Others use standard stranded fiberglass like the original. I've seen spray ceramic used. Others use the bubble type, or it's cousin Reflectix. Some have used hard foam boards.
Some folks cant commit and use a combination!
FWIW, I used reflectix because I hate itching, it's not permanent like spray in, my roof curves too much for big chunks of foam board and I'm too cheap to use the $$$$ ceramic stuff...
