Sungold, and tumbling tom are the types I have lots of success with. The last couple of years we have had poor sunshine so larger toms have a hard time ripening. With this in mind I'm trying 'sungella' which is a cross of sungold, but the toms are the size of golfballs so I'm trying to find the happy medium of size but still ripen. I shall post my results throughout summer. I grew a Heritage variety last year 'black russian', they were nice, but more difficult to grow mainly because they got as large as your fist, and needed major support, they then took an eternity to ripen!
Because of the poor sunshine levels the last few years, I'm put off from growing beefstake varieties, whereas the sungold and sungella gave me literally 10 carrier bags full of fruit.
Be aware I grow in a large 10x12 greenhouse, lots of my friends with allotments who grow outside have been decimated by blight the last few years.
