If you've decided you want the best gas grill Weber makes, these are your two real choices. The new Genesis SPX is the modernized flagship — Smart Grilling Hub, refined design, integrated probes. The Summit S-470 is the proven workhorse with 4 burners, sear station, and side burner. Same brand, very different feel.
Quick Verdict
Buy the Weber Genesis SPX-435 ($1,899) if you want the most modern, app-connected Weber gas grill with integrated probes and an updated cooking system. Buy the Weber Summit S-470 ($2,099) if you want a proven, feature-loaded grill with the rotisserie burner and side burner included.

Cooking System
Winner: Genesis SPXGenesis SPX wins. The new Smart Grilling Hub, PureBlu burners, and angled flavorizer bars represent Weber's most refined cooking platform. The Summit's system is excellent but generations older.
Smart Features
Winner: Genesis SPXGenesis SPX wins decisively. Built-in probes, full Weber Connect integration, ambient and food temp tracking. The Summit has zero smart features — it's a pure analog grill.
Burners & Versatility
Winner: Summit S-470Summit wins. 4 main burners, dedicated sear station, side burner, AND infrared rotisserie burner all included. The Genesis SPX is feature-rich but the Summit has more raw cooking hardware.
Build Quality
Winner: TieTie. Both are top-tier Weber construction with 304 stainless and 12-year warranties. The Summit feels heavier; the Genesis SPX feels more refined. Both will outlast their owners.
Value
Winner: Genesis SPXGenesis SPX wins. $200 cheaper for the more modern grill with smart features. The Summit's extra burners are valuable but most cooks don't use the side burner or rotisserie weekly.
Final Verdict
Buy the Weber Genesis SPX-435 if you want the newest, smartest Weber gas grill and don't need a rotisserie burner. Buy the Weber Summit S-470 if you'll actually use the rotisserie and side burner and prefer analog simplicity.
Buying Advice
If you cook rotisserie chicken weekly, the Summit's infrared rear burner is genuinely irreplaceable — go Summit. Otherwise the Genesis SPX is the smarter buy and the more future-proof grill.
