according to gsm arena, the sd888 vs exy, the sd888 has like 10 to 20% performance and endurance lead..Is it worth to spend extra to buy the SD888 variant for S21U?
of course YMMV..
and the exynos enters thermal throttling way faster that the SD888
but if you just using phone for facebook, whatsapp and email, then probably won't kena all these.
