3s Flightmax vs. 3s Turnigy

hi,

because i will order a e-revo i must sell my a123 batterys and buy 3s lipo.
on hobbycity the 3s 5000 flightmax are out of stock, but the 3s 5000 turnigy are availible.

i think both will fit in a e-revo and my other cars.
are the turnigy recommended or its better to wait for the flightmax.

i used a 20c 5s 5000 flightmax in a lst2 and runs fine and cold.
i think 20c will be enough for lst2/x2 crt/e-revo.

whats the better battery?
