If normal conditions means not too much surface trash and mild ground mineralization, probably not if you are just looking for silver/high conductors.
If there is lots of non-ferrous, mixed alloy trash and any thing worse than mild mineralization, the Manticore will have a big advantage.
I owned an Etrac and still own the Manticore. I often hunt in moderate to heavy modern trash with moderate to high iron mineralized ground. The Etrac running it the recommended way which is with tracking ground balance, would end up on sensitivity 10 to 12 which means 6" depth at the most where I detected with it. The equivalent on the Manticore would be running it at 14 sensitivity. If I turned off the automatic tracking and tried to run my Etrac at a higher sensitivity, the ground noise was impossible. I can run the Manticore at 26 to 28 sensitivity on the same ground with no ground noise. So huge advantage to the Manticore for ground mineralization handling.
Weight and target separation/recovery speed have already been mentioned. Targets on edge, partially masked targets, other targets besides high conductors, other sized targets besides coin sized, not waterproof, no wireless audio, no internal rechargeable battery, no lightweight collapsible shaft system, no big audio options and most important for me, no restrictions on where I can hunt with it and what I can hunt for....... Manticore beats Etrac silly except on deep silver and that is only true for almost perfect ground conditions.
Minelab are not dumb. They knew that the Etrac was just for a very specific situation. If you were a person like me that did not hunt in that specific situation, you were screwed until the Equinox and Multi IQ was released.
I found 2 silver coins here in Colorado using the Etrac for a year in public parks. Same public parks, I found 89 silver coins and 48 silver rings last year using the Manticore along with some deep gold rings. All were 8" deep or deeper.
