Wilja is a great all-rounder. King Edwards for roasties. Maris Piper is good.
I grow some at home in potato sacks - Crystal, Duke of York, Wilja and Home Guard all did well last year. Grew some DOY for winter cropping - Dec/Jan/Feb - fine as long as you can keep frost-free - the tops were killed on mine at the end of December, but they keep fine in the soil & I just fish some out as and when I need them.
