I have taken driving lesson's in both. Manual isn't that hardalthough i did have problems with clutch control too but fear not you can overcome this.

The reason why i switched to Automaticwas because i use to get bad crap whilst doing my lesson's and changing the gear ever so often initiated and worsen the crap.
It depends on your reason's and preference if manual is reallycausing you too many problems try afew lesson's in auto just to see how you progress and distinguish between the two,but it's best topass in a Manual car and thenpurchasean Auto because once you pass your driving test in an auto you can't drive manual car'sunless you re-take with a manual.
