I’m currently having a good experience with MikroTik. I think their products provide a good combination of features and pricing. There are a “CRS317-1G-16S+” and a “CSS326-24G-2S+RM” in my rack and I have my eyes on the “CSS610-8P-2S+IN” as a efficient little POE switch.
I haven’t used Ubiquity, so I can’t compare these two brands.
For APs I’m currently using TP Link Omada with a selfhosted Omada Controller and for Routing, DNS, Firewall and stuff I use OPNsense.
I use Wasabi S3, but only for my most critical data. For full backups including large media I setup a offsite NAS.
Regarding tooling I’m really happy with Restic (coming from Borg).
