not necessarily.
By accurate I mean reads closest to what the actual dB level is. The B&K is probably just as accurate as the TL, but the B&K can be affected more by temperature, air pressure, etc.
Plus different B&K's will read differently from each other, moreso than a termlab will.
The most I've seen two termlabs read differently from each other is ~.2 dB. That can't be said for any other meter, imo.
Thats what I meant by consistency. It's consistency within the meter itself and between different meters.
