i think lower speed is always better for quality of record
The "Quality" of the Audio Data, or the Integrity of the data should be the same as long as the burn validates/verifies as OK (Like the 2nd post said). Else you have a failed burn, and have to burn the disc again.
Of course, for archiving I wouldn't use optical media anyway.
There are programs that will test the quality of a CD or DVD in terms of number of correctable and uncorrectable errors. One that I used years ago was by Nero, but I've forgotten the name.
