The value here is the low pricing that Airtel Kenya is offering for their router which is affordable. However, Safaricom on the data package offer has more value up to 50 Mbps with the free router compared to Airtel Kenya's. All in all, it will depend on the kind of infrastructure in place. It should be noted that Safaricom has been consistent on pricing, if you go too low, one cannot invest in infrastructure and maintenance.
