What is the best wardriving client for getting the most accurate/best triangulation?

Also, does using the merge feature in NetStumbler toss out data?

-NB

Any client that logs a new line in the file each and every time it sees an AP will work. I've noticed that KisMAC doesn't do this (or didn't a year or so ago) and I don't think NetStumbler does either.

My 'driving logs with dstumbler (part of BSD-Airtools) are something like 6-8MB each when I've been delivering pizza for 3 hours or so. Each time it gets a beacon from an AP, it logs the location and adds a new line to the file.

Here's a sample. One access point that I saw while I was on the move, and the different locations I saw it from:
Anyhow, That's just a small subset of all the locations I saw it at, but for an example this shows how it works.

The main thing to look for is the log file sizes. If you have huge log files, it's probably keeping track of every single location and it can triangulate them. If your app has small log files, like less than 200k, it's probably not logging each location. It might be, but I doubt it.
