With some trepidation I will dip my toe into discussions concerning a 6000 as I don't have one but am confident enough with the feedback to get one for my next season.
I agree with DALEO8 and think so much does depend on preferred coils and settings that we chose, and for that reason there is considerable overlap in the subjectively perceived performance between detectors.
As an example I sold my 2300 last year and rebought a 5000 for the specific purpose of returning to deeper gold finds. It came with an 8" commander coil which is the same size as the standard 2300 coil, and I thought I'd give it a go on the 5 in fine gold setting going over ground that I had worked well with the 2300.
The results were interesting. The 5 and 8" combination had no trouble picking up similar numbers and sizes of nuggets to the 23, but clearly a lot were coming from deeper and a few were significantly larger bits missed by the 2300 on my "patches". This was offset in some way with the very tiny nuggets that the 5 missed but given the much less time using the 5 the results would have been on track to give me if not necessarily larger numbers but enough to keep me busy and certainly a larger weight of gold.
It seems interesting that people feel that the 6000 is in the ball park when it comes to depth with a 45 (or 5 presumably) as well is its well documented success so far.
Not yet ready to give up my 5 yet because of its potential to use large deep seeking coils but feel that a 6 as a companion detector will be my next step.
