Our team's captain uses a Burn-aratox for two seasons now and didn't have any issues so far.
But i've only hit with both of your mentioned blades for a couple of minutes, so maybe someone who has used both of them longer should be more helpful.
One thing I can say for sure though, i really don't like these hollow Senso handles anymore. I've used a Persson Powerplay Senso for half a year, 3 years ago and what I don't like is, they tend to get real 'head'-heavy if you use thick rubbers.
