Difference in results with Wordze and Wordtracker

Hi everyone,
I purchased Wordze member account sometime ago because it's cheaper than Wordtracker, but now when I'm comparing the results from Wordze to Wordtracker free keyword suggestion tool, there's a really huge difference in search counts

So I'm not sure which one should I trust more. Does anybody has any experience with this, or has knowledge which one is better? For sure I can pay more money for Wordtracker if it's more accurate
Thanks

P/s: I just compared one keyword on both Wordze and Wordtracker. In Wordze it has 1888 counts, and in Wordtracker it only has around 300 ...

Wordze (I don't know it), WordTracker, KeywordDiscovery... you will never get the same results because they don't use the same sources/data ie one of them will include such and such search engine, the other one only such and such etc... sometimes over different periods of time...

Also, WordTracker free research tool doesn't include Google as far as I can remember, so to get the overall number of results you'll have to x10.

I use NicheBot which is using WordTracker, KeywordDiscovery, Google etc... API to provide all of these tools together with other keyword related services as well. However they probably got kicked from KD because it's not available anymore from their site (both the quick and deep digging tools).
