Panda Wrap VS Mylar

Hey folks, I just wanted opinions on what I should use to reflect as much light as possible from my 2 1000 watt lights. Im stuck between Panda Wrap and Mylar, what reflects more light?

I like using panda vs mylar

For me the panda is easier to work with.Easier to put up and easier to keep clean.

Another vote for panda.

One more for panda, I've made walls with that shit, split rooms in halfs AND was still able to keep the flower side light tight. Can't do that with Mylar.
