I dont think any one can say which one is best fully automatic or semi automatic because they both depend on the uses of you.
FULLY AUTOMATIC.
this machine is useful for that people who dont have time for change the tub of cloths like washing tub to drier and do other things specially perfect for the working woman who want finish their loth work in just one time. just attach the machine with all things and now do other work. in that case its perfect.
SEMI AUTOMATIC.
this is perfect for home makers because it can do both work together like washing and drying. maximum time the home maker have lots of cloths to wash so she can wait so much time so in that case semi automatic is perfect for you.
so there is both machine benefit now you can choose according to your uses.
