Which is the better series?

Hello all!

I was considering starting the series and wanted to know what the fan base believes is the “better” series: the original from the ‘70s, or the one from the 2000s?

I’m still reading about the series to see if I’m interested, but I’ve heard a couple of quotes and I love militaristic sci-fi; Aliens and Starship Troopers are some of my favorite movies.

Thank you!
