What do the top of the line Netgear switches i.e. M4300 series not have that Cisco & Juniper do for the SMB environment?

I have setup Netgear M4300 series switches at 3 sites now and all have been running for a year without a single issue.

These switches have many enterprise features such as:

1. Redundant Power supplies
2. Advanced topologies such as spine & leaf with switch stacking
3. Out of band management
4. Full featured CLI and WebUI with secure login
5. VLANs, layer 3 routing, DHCP, ACLs, LAGs, etc
6. 24/7 pro support for very reasonable cost
7. Lifetime warranty with part replacement

Some of the things these switches don't have that I have noticed on some comparable Juniper and Cisco switches.

1. ECC memory
2. Multi-core processing

Opinion The cost for comparable Juniper and Cisco seems to be about 3x. So, I could buy 2 sets of the Netgear and leave one on the shelf in case anything breaks and still be saving money. Just seems a bit ridiculous.
