HP 1620/1820/1920 which one to choose?

Question

HP

I choose 8-port and 24-port.
1820 is the cheapest, 1920 and 1620 cost almost the same.
Task: Internet in several apartments with a large number of IGMP. Also QOS.
From Description 1620:
Quality of Service (QoS)
• IEEE 802.1p prioritization with DSCP
delivers data from the switch to devices based on the priority and type of traffic using Differentiated Services Code Point
(DSCP).
• Broadcast control
allows limitation of broadcast traffic rate to cut down on unwanted network broadcast traffic.
• Rate limiting
sets per-port ingress enforced maximums and per-port, per-queue minimums.
From the description of 1820:
Quality of Service (QoS)
• Traffic prioritization
Provides time-sensitive packets (like VoIP and video) with priority over other traffic based on DSCP or IEEE 802.1p
classification; packets are mapped to eight hardware queues for more effective throughput.
• Broadcast control
Allows limiting of broadcast traffic rate to reduce unwanted network broadcast traffic.
• IEEE 802.1p/Q
