+1 for the Garmin GPSMAP 66i. Nice unit and good battery life(3 or 4 days on a charge). Seems fine in cold also. I do have the minimum monthly Inreach contract, which I use to track at 20m intervals in remote areas. Mrs insists on it, presumably to find me if I peg it and get a swift life insurance payout 
I have a free Topo Map with contours, hillshading and hiking trails from Overview. It normally just stays in side pocket of rucksack tracking away. Use OS 1:25000 stored on phone as primary. Plus a Garmin Instinct watch with compass and breadcrumb of my track! Great for getting off a summit again with zero viz.
I have most of the Scottish Highlands in 1:50000 OS Landranger, used to carry all the time but stopped earlier this year. Never pulled them out for a couple of years. Compass still in pack, but feels pointless when I have another 3 on devices.
I would consider myself proficient with paper map & compass, but quite happy to dump it now. See less and less people with a paper map now.
I think the key is having a backup and not just rely on a single electronic device for all navigation.
