Sure, Enoch, happy to do so, so long as everyone realizes this is only my personal opinion. Commentary preferences vary widely from individual to individual. Also, I can only provide an overall impression of these as commentary series, since each set has individual volumes that simply shine.
The NICOT/NT commentaries have been my "default" commentaries for many years. In fact, they are still the standard by which I compare other commentaries. They are solid, trustworthy, and generally take the "scholarly consensus" position on most issues. Most of them have been around quite a while now and, that said, some of them are getting a bit dated.
The WBC OT/NT commentaries are generally newer, which allows them to take advantage of recent advances in scholarship. They are also a bit more technical than the NICOT/NT (which means they devote more attention to the original languages and their grammar). I like both of those things. Like the NICOT/NT, the authors in this series generally take commonly accepted positions.
