I don't have experience with the Venus Z, but I have a per my last email and a finally v2, The finally definitely sounds warmer/thicker/fatter than the PMLE set flat, although boosting a little of the lower end changes that, however it's a slightly different flavour of it. This is with the gain in the finally turned up around 1 or 2 o'clock and a 12AT tube in there at the moment, with it backed off they have more similarities than differences.
I like the finally for the sparkle and richness it brings to the sound without sounding brittle or lacking body to it (I know, buzzword bingo), the PMLE is great for a more modern sound without it sounding ice picky or 2 dimensional, but if you're not using the EQ, and are unlikely to (which I think is a shame as the EQ works brilliantly) then the finally might give you more of what you're looking for?
