In North America it is pretty rare to see a stick style Tx for a RC car or truck. Nearly everyone uses pistols.

Looks to me that over in the UK you have many more folks using the sticks.

I find the pistol grip very intuitive to use and easy to hold. It'd be pretty hard to convince me that i'd have finer control with a stick type tx.

Your best bet is to find someone who will let you try their pistol radio for a while, and see how it suits you.
