Which one should you buy?
ASUS ROG Swift PG279Q 1440p 165Hz
Choose the ASUS ROG Swift PG279Q if you specifically want hardware G-Sync (not G-Sync Compatible) and are committed to NVIDIA GPUs long-term.
Dell S2721DGF 1440p 165Hz
Choose the Dell S2721DGF if you want the same IPS panel quality with both AMD FreeSync and NVIDIA G-Sync Compatible support at a meaningfully lower price.
What the spec table doesn't show
The Dell S2721DGF carries both FreeSync Premium Pro and NVIDIA G-Sync Compatible certification — meaning it fully supports variable refresh rate with AMD and NVIDIA GPUs. The ASUS ROG PG279Q uses a hardware G-Sync module (not G-Sync Compatible) which adds to the cost but provides no perceptible image quality or latency advantage over G-Sync Compatible on modern NVIDIA drivers. NVIDIA's own testing shows G-Sync Compatible monitors pass the same VRR standards as hardware G-Sync.
Verdict
For most buyers the Dell S2721DGF is the better value — same IPS panel technology, works with any GPU, and is typically $50-100 cheaper. Only consider the ASUS ROG PG279Q if you find it significantly discounted, specifically want ASUS ROG build quality, or are using older NVIDIA hardware that pre-dates G-Sync Compatible support.
