Had the Ares, Orthos 2 and Gemini. The basic core tone is fairly similar as the Crunch and Lead tones are basically the same. The biggest difference is the Gemini having way more modes and switches to coax a wider variety of tones than the other 2 amps. The Ares is a basic 50 watt dual Master amp with both the Crunch and Lead and the Orthos basically takes that amp and adds a dedicated clean channel, plus the option of 100 watts. The "Feel" knobs are cool to adjust the overall tightness and tone of the amp. They do more than just loosen or tighten the amp so it helps to experiment with those. The Gemini was a super cool amp but I felt like I was fucking with switches too often and it didn't offer me much more than the Orthos could. I also don't need Midi so that was another downside to that amp. Give me a simple 2-3 channel amp with a basic foot switch.
