Charge rates @ C/1 are fine including your AAAA's as long as the charger algorythm is geared for NiMH, and not NiCD.
There seems to be some unfounded concerns about charging regular duty (consumer or commercial grade) NiMH cells at anything <C/10. This is simply not true with modern NiMH cells (modern meaning typically lower internal impedence due to updated design/manufacturing practices). As far as no name (something you buy at Walmart, etc) versus name brand (eg: Sanyo), there are differences in design and manufacture that may cause the no name to demonstrate a lower mA/Hr, and/or fail earlier (electrically or mechanically). This shows up when a cell is subject to higher current rates, and/or severe mechanical loading. "Higher" current rates in this case can be considered double what the OEM rating was in the first place to determine Ma/Hr (if a cell is tested @ 200mA, then 400mA would be considered higher). So yes, there is a marked difference between consumer grade, commercial grade (which is what we tend to see most often), then up for there. If you are employing button-head equiped cells, most likely they are consumer grade, and do not have typcial means for venting in the vent of failure (not enough poop to cause a problem).
