Communities Deployment Hell so Communities they are split into multiple things in the backend a Network a Site and some other free floating shit like the guest user, profile access, etc. Network is what you think about when you read Communities it's where the comm builder etc lives the Site is how they exposed it to the world. it's a legacy feature wrapped in a new one the Site as detailed in my longer rant used to be where you handled translations and shit, because OF COURSE that was a good idea, anyway. when deploying a community you have a two options "bundle" it with a Lightning Bundle as they call it, which is basically a template of your community this works nicely but doesn't include everything about the comm (I forget what exactly but some stuff like branding etc wouldn't get carried over as well as some custom pages) or pushing the Network and the Site via Changeset or API. now via API is what Gearset does. The good point of API deployment is that you can target the network site, and related StaticResources and other shit directly it's easy enough the bad thing is that API deployments rely on the backend structure being sane, which is isn't. Example: if you have two object `REALLYLONGPREFIX_stuff__c ` and `REALLYLONGPREFIX_shit_c ` the backend stores a truncated version of the page so if you do custom pages this results in you having the pages being possibly misattributed to the other object or vice versa or overwriting the other page at random everytime on deploy Q U A L I T Y. the API deployments are also less fault tolerant than changesets meaning if something's missing it'll just completely fail and some of the community errors are quite arcane specifically the ones related to Site deployment so, changesets ? well changesets aren't much better you can still get the arcane Site deployment errors, thoughtless of them because it resolves some missing shit on its own for some reason ???? but what's nice is that the community elements will save in whichever order so for example you can completely have a community that'll deploy but fail because the Asset for the custom logo of the banner is missing even though you included it in the changeset so now you gotta deploy the asset alone and then deploy the community which will STILL say that the deployment FAILED but show you a green checkbox saying "deployed successfully" which will actually mean it deployed successfully because the only failed elements are the Assets. nope, still not kidding. now for easy ass communities you might get a deploy that goes well and SF may hotfix some of those issues but in the meantime it's better to consider the entire deployment process hell plan more time for it than needed and if it's simple in the end well that's awesome.
