I personally find Mobile or desktop apps A LOT less stressful, deadlines are usually much more reasonable. On iOS at least if the app works on your test device it's VERY likely to work on the device in the wild. Given the nature of the App Store "hot fixes" are a lot less of a thing. Also given the release cycle it's often common to have a lot better of a QA process in place. In general you only need to be an expert in one or two languages (swift/kotlin or Objective-C/Java if you cover both OS's). I'm a full time mobile developer and I love it.
