17.3.5 or 17.6.4 | C9300L-24P-4X-E

[emory.clayton]

Looking for an upgrade suggestion for a C9300L-24P-4X-E. The link below suggest 2 different versions (17.3.5, 17.6.4). They will not be doing anything fancy other than L2 switching (I know, its overkill, its what the clients Administration wants). Other than looking at the affected bugs related to both, and choosing the lesser to 2 evils, what other ways would you go about deciding which one to go with?

You're suggesting to go with 17.6.4 simply based on the release date?

If anyone is brave to even consider 16.12.X, please refer to my "documentation" below: 3850 (4 x switches), Firmware version: 16.12.4, Uptime: 1y43w4d

9300, IOS-XE version 16.12.4

3850 stack, 16.12.6
