Thay have to be 'Joan J' here, Wbmkk!
They're easy to grow, you can prune with a hedge trimmer after fruiting, they only need bit of taming just before they fruit, so a bit of string here and there doesn't go amiss, and the fruit is just fabulous! The season can easily go on for weeks in a good year
If you can feed them before they get fruiting, you'll be rewarded with a great crop of huge berries!
