Motor and ESC Advice

[m3nf]

I seemed to have either blown my motor or ESC on my rc10b4.1.

I wanted to find out a few basics while i am replacing them both.

I like to keep the sensorless system, so i have brought a 60a ESC, so i can also run a faster motor.

On my old system i gathered it was a 35a ESC and a 3300KV motor, not sure of the 'T' rating for it.

I bid and won a few motors on eBay, and wanted to ask as which would be the best.

These are the ones i have brought

Sensorless Motor Brushless 13T 3200KV
Motor Sensorless Brushless 12T 3200KV
Motor Sensorless Brushless 9T 4370KV

Could you please explain which would give me the closest to my original setup, and which would give a better top speed and if which would be best for acceleration.

Many thanks all for any help.
