Verdict
The RX 6600 and GTX 1660 Super land at effectively the same price so your decision should come down to features, ecosystem fit, and availability rather than budget.
As an NVIDIA card, the GTX 1660 Super gives you access to DLSS 4 super-resolution and Frame Generation, which can meaningfully lift frame rates in supported titles. The RX 6600 counters with FSR 4, which is open-source and works across a wider range of games — including some that don't support DLSS. Which ecosystem matters more depends on the games in your library.
