There is no doubt that Keil is better supported from our side than GCC/Eclipse, for example since only the heart rate BLE example is available for GCC. 
 However, if you're ready to fiddle a little yourself, there shouldn't be any major problems with using Eclipse and GCC for the nRF51822, and we'll try to help you as best we can if you hit problems. There have also been several questions here on Developer Zone that might be useful to refer to.
