I don't know if you have seen these, but I've been working on some new 
T2 wiki pages to break up the different types of configs onto separate 
pages, and expand on the advantages of each.  The pages can be found at:

http://wiki.opennicproject.org/Tier2ConfigBindHint
http://wiki.opennicproject.org/Tier2ConfigBindSlave
http://wiki.opennicproject.org/Tier2Security

I will be rewriting the current config page as a front-end pointing to 
these various other pages.

But in regards to your question, it doesn't make any sense that the 
hints configs would be more reliable than the slave configs... I would 
expect exactly the opposite to be true!  Keep in mind that the servers 
configed with hints files are doing nothing but pointing users to 
*other* tier-2 or tier-1 servers to complete their query, so you end up 
relying on a greater number of servers being operational to get an 
answer.  On the other hand, a slaved server has all of the zone files 
stored locally, so it is able to directly answer any queries coming in.  
Sure cache size can be important, but you can set your cache to a custom 
size on any of the config types.
