Recovery Question topic

I read that many people are very pleased with Phil's recovery, and I'm a bit noob so I'd like to understand some thing:
1)I'm now on scanno twrp and kikat cm11-10012014, and can I install it via terminal emulator?
2)If I install it will I be able to go from Cromi-x to CM11 without the need to change recovery?
3)I understand that twrp is not that safe with cm11, and many people get bricked devices...is Phil's cwm more safe?
