Is the RGB version worth the extra $10?

Only if you want lighting. Speed, capacity and latency are the same, so you pay $10 for RGB and wider store availability.

Which is better for a Ryzen build?

Both are rated for AMD Ryzen and use XMP, not EXPO. Either works; pick A to save money or B for lighting.

Will the RGB heat spreader fit under a large air cooler?

It is taller than the non-RGB version. Check your cooler's clearance; the low-profile A is the safer fit.

Do both run at 3200 out of the box?

No. Both default to 2666 via Plug N Play. You enable the 3200 CL16 profile in BIOS with XMP.

Which has been cheaper lately?

A ranged from $218.03 to $239.99 between October 30 and November 8, 2026. B's price history was not given, so compare live prices before buying.
