SRAM and Shimano are in a dead heat quality & price wise. I speak from extensive experience.
One important detail…SRAM 11 speed cassettes start at 10t and require an XD drivetrain. Shimano starts at 11t and fits the same old cassette body we’ve been running forever. SRAM and Shimano components are not interchangeable piece by piece as they once were. Not a huge deal if you are happy with SRAM but for those with an overflowing spare parts box, or a backup rear wheel, or bargain bin shoppers it could be an issue.
