I've had problems with xmr-stak crashing, on startup, on 2 different rigs but working OK on 3 other rigs, unfortunatley never figured out why xmr-stak kept crashing, so was forced to use Claymore's CryptoNight miner.
I found that xmr-stak would run my GPUs a little bit cooler and with a little bit less electricity costs but at less hashrate.
The Cryptonote miner I prefer is SMminer-gm-5.5.5, it gave me a little bit more hashrate than Claymore and it ran at lower power consumption, so this was why I prefered to use it.
