After riding a 1x set up for the past 3 years I can say without a doubt that I won't run a front derailleur ever again. Sram is the company that brought a reliable 1x drivetrain to market and they haven't stopped updating since. Eagle is the newest rendition and once again Sram has made a great thing better.
The range of this cassette is amazing. Riding here in Utah I almost never need to use the 50T cog out back. However, I've been able to run a larger chainring up front to achieve higher speeds without sacrificing my low range.
If you're looking to go 1x and want the best range on offer I recommend looking at Eagle X01. Below is the gearing for this cassette.
10, 12, 14, 16, 18, 21, 24, 28, 32, 36, 42, 50
