Id say if they arent at risk of other fish eating them, let the parents look after them. I have been breeding angelfish and kribensis for a long time now and know that the best fish are the ones left to be raised by their parents. Also they are then better at breeding themselves. The parents may eat the eggs or wigglers on the first or second go and if this happens then just leave them to try again, if it happens more that 4 or 5 times i start taking the eggs out of the tank and hand rearing but I have found that angels like to be with their parents and generally i have had a lower mortality rate with them left in there. Lastly, taking them out requires a much larger effort on your part, making sure the eggs are well looked after and dont go mouldy, making sure there is enough water movement past them, feeding them properly and keeping them from any filters etc.
If you do decide to take the eggs out, you will have to have an established tank already set up with an airstone close by to the eggs. Also go and buy some meth blue which will stop them from growing fungus on the eggs. Make sure there is no gravel in the tank as if they are wigglers and they fall (more likley if parents arent there) they can get trapped in the gravel and die. When siphoning, make sure any you suck up are put back in and check water parameters constantly making sure you do regular water changes.
