You're looking at three distinct Noida societies, all in or near Sector 124, each with a different profile. M3M The Cullinan is still under construction but lands the highest SocietyFlats score (8.0) with premium amenities and a ₹9.28–17.5 Cr buy range. ATS Knightsbridge is ready now, slightly pricier (₹18–31.5 Cr), with strong sports facilities and verified rental data at ₹63,000/month. ABA Cleo County, in Sector 121, offers the widest rent range (₹55,000–2,00,000/month) and the lowest entry buy price (₹2.8 Cr), with excellent metro proximity. The real choice here hinges on timeline, budget and whether you prioritize space or commute ease.
M3M The Cullinan tops the scores (8.0 overall, connectivity 8.1) but won't be ready for a while. ATS Knightsbridge is move-in ready with a strong lifestyle score (8.2) but costs significantly more. ABA Cleo County combines the best metro access (1.8 km to Sector 61) with the lowest entry price and most flexible rent options—a real value play if you're budget-conscious or want short-term flexibility. All three sit in similar sectors; the trade-off is timeline and price, not location.

M3M The Cullinan — M3M The Cullinan is a large-scale luxury project still taking shape in Sector 124. When complete, it will feel refined and feature-rich: the sky clubhouse, infinity pool and spa suggest a lifestyle-first builder. Connectivity to metros and business parks is strong (2.2–4.1 km). The trade-off is you're buying into a timeline—possession is still pending, so this is a forward bet.
ATS Knightsbridge — ATS Knightsbridge is live now in Sector 124, ready to move into today. The DNA here is sports and recreation: tennis, basketball, badminton, cricket nets and a private 30-seater theatre set a clubhouse-centric tone. At ₹63,000/month rental verified, it's priced as a premium ready option. You're paying for immediacy and curated amenities, not cutting-edge specs.
ABA Cleo County — ABA Cleo County, in Sector 121, stands out for flexibility and access. It's move-in ready, offers the widest rent range (₹55,000–₹2,00,000/month depending on unit and lease term), and sits closest to Noida metro hubs (1.8 km to Sector 61). The design emphasizes green space—cascading pools, golf course, mist garden—and plays well for families or those who want outdoor breathing room without mega-premium pricing.
ATS Knightsbridge and ABA Cleo County are both ready to move. M3M The Cullinan is still under construction, so if you need to shift soon, those two are your live options. ATS Knightsbridge rents verified at ₹63,000/month; ABA Cleo County offers much wider rent flexibility (₹55,000–₹2,00,000/month).
ABA Cleo County wins on metro proximity—Sector 61 Noida is just 1.8 km away, and Noida Sector 51 is 2 km. M3M The Cullinan and ATS Knightsbridge are both roughly 2.2–2.4 km from Noida Sec-18. If your office is south of the NCR and you use metro daily, ABA Cleo County saves you commute time.
ABA Cleo County is the entry point—buy from ₹2.8 Cr and rent from ₹55,000/month. M3M The Cullinan starts at ₹9.28 Cr. ATS Knightsbridge is the priciest (₹18 Cr+). If you're renting first to test the area, ABA Cleo County gives you the most room to manoeuvre on monthly rent.
M3M The Cullinan emphasizes premium lifestyle—think 100,000 sq. ft. clubhouse, spa, multiple themed lounges and EV charging.

Your choice depends on whether you value polish, sport or space.
