Now is really not the time. The Home Office will have an extra ~3m permanent resident applicants over the next year, as all EU nationals are made to go through the process.
Most (but not all) will go through the expedited "settled status" process. Those not eligible or rejected for dumb Home Office reasons will have to apply for ILR. https://www.gov.uk/settled-status-eu-citizens-families
Speaking to my immigrant colleagues it sounds like it's all fine unless you hit Home Office bureaucracy, in which case it can rapidly turn into an expensive nightmare.
