I can't tell the difference from the Lounge Copla and TZ Vibe. The TZ zeroes out the load impedance still with the Copla you have more options for gain and load to your taste.
I was unfamiliar with the Copla, but the Lounge website says:
“[The] Copla is a moving coil step-up amplifier designed to drive a moving magnet phono pre amp. It is the active electronic equivalent of a step-up transformer (SUT), allowing control of active moving coil impedance. One dial provides variable added richness and dimension to the response of your moving coil cartridge. You use it like a Tone knob.”
The TZ Vibe is a full phono preamp exclusively for low impedance MC cartridges. It uses transimpedance amplification instead of voltage amplification. Totally different designs for different (but related) purposes. Look for reviews of the Sutherland Little Loco Mk2 to get a comparable reference to the TZ Vibe.
