In my experience one of the big differences between backend and frontend (and even app development) is that frontend development has an incredibly fast rate of change. What are best practices now might be considered code smell in 3 months. The tempo, in which the technologies are being swapped out and the number different general directions (react vs vue vs angular vs traditional server side rendered,...) make frontend hard in the sense that keeping up with the fast pace of changes takes up quite some time and energy. I think that the pace of change in the underlying technologies is a lot slower on the backend and that you can even get away with being an expert for "legacy" technology for quite a while. Another huge difference is your impact on the UI/UX. Working on frontend always means that the developer has direct impact - and responsibility - about many details of the final product that noone else might have thought about. If you're into this type of work perfect, but if this stresses you out frontend might not be the right fit for you.
