TWRP or CWM?

Hello,
i would like to install a custom rom to my china smartphone coolpad 1S with CPU: mtk6592T (armv7 processor rev4(v7l). instruction set: armeabi v7a)
I found many custom roms for my device (for example, the MIUI V6.0),
but i didn't find a simple guide to flash the rom to my device.

I found only that , to install the custom rom, i need to install a recovery TWRP or CWM.
And i found that i need to create the recovery.
To do this, i found that i must use one of the following tools:

MTKdroid tools, to generate/install the CWM
or
EasyMagic TWRP, to generate/install the TWRP.

I would like to know which of the above is the easiest and safest to be used for my phone.
And, finally, if to install the ROM i need a tool, or if i simply can flash it booting my phone in recovery mode.

Thank you!
