I mean compared to other exchanges. I use Kraken as well and i've never had any fiat withdrawal problems there.
The other thing that bugs me is that they don't even admit to having problems. They tweet about having processed billions worth of withdrawals in October, yet they can't process mine and those of other people i've read complaints from?
Kraken's had their fair share of problems too, primarily with USD. Their EUR banking relationship has always been rock solid as far as I can tell.
Bitfinex themselves have said they bank like criminals, opening shell accounts and keeping banks in the dark. That's not going to be conducive to smooth sailing. And of course they had no banking for months a while back.
I wouldn't ever bother with them for attempting to obtain fiat. There are better options and always have been.
