I think the plus four post 2014 or the gdi variant is the best of the bunch. It comes with the look of a traditional morgan but has many more refinements such as power steering heated seats galvanised chassis uprated kingpins good brakes
The power from the gdi is enough for fun on b roads and can hold its own on a motorway
I have driven lots of morgans of all ages and the gdi in my own opinion
Like all things morgan its personal choice but after 12000 trouble free fun filled miles I can not fault it
