Having raised masked & fischers, as well as peachfaced, here is my opinion. Masked, even handfeds, can be very flighty. They need to be handled alot more than a peachie to keep them nice and they can be nippy. Fischer's can also be flighty, but are also very sweet. I've not experienced the nippiness in them that I have with the masked. Again, this is JMO.
