The how of mesh doesn't matter.
From the documentation -
Impact of Meshing on Throughput
Due to the half-duplex nature of wireless communication and that signals being passed through a repeater AP must be retransmitted to the next hop, throughput is greatly reduced when using a repeater. While many factors impact wireless throughput, it is safe to assume that the addition of meshing can reduce throughput by approximately 50%, with that reduction being applied for each subsequent repeater that must be traversed to reach a gateway. Therefore, it is advised to minimize the number of hops between a client and gateway.
In other words, "Avoid meshing like the plague".
Unfortunately, WiFi manufacturers operate on a SWAT principle, so they are delaying switching to IEEE802.11ad technology which has sufficient bandwidth to spatially separate the backhaul traffic from the rest of the WiFi packets, which offers some amelioration to a basic issue of physics. Probably, WiFi technology as currently implemented is overdue for a complete replacement, there is no other way to overcome the physical limitations of Half Duplex communication.
