Quick answers

Is the Anker SOLIX C2000 Gen 2 better than the Oupes Mega 2 Pro?: Oupes Mega 2 Pro takes recharge speed, Anker SOLIX C2000 Gen 2 takes weight and noise — the decision is which of those you need, not overall quality. If neither is your constraint, the composite tiebreak goes to Oupes Mega 2 Pro by 1 point — a hair, not a mandate.
Which has more usable capacity, the Anker SOLIX C2000 Gen 2 or Oupes Mega 2 Pro?: Neither, in any way you would notice: 1,761 Wh against 1,741 Wh is a 1.1% gap, which is smaller than the swing you get from running the same load on a cold morning. Treat them as the same size and decide on output, weight, or today's price instead. Both figures are estimated AC-delivered energy, not the nameplate battery rating — the watt-hours that actually reach your devices.
Which has more AC output, the Anker SOLIX C2000 Gen 2 or Oupes Mega 2 Pro?: The Oupes Mega 2 Pro: 2,400 W versus 2,500 W continuous. That gap matters only if a load sits between the two numbers — below 2,400 W both run it, above 2,500 W neither does. Surge headroom follows the same order: 4,000 W against 3,800 W, and surge is what decides whether a compressor or pump actually starts.
How does runtime compare between the Anker SOLIX C2000 Gen 2 and Oupes Mega 2 Pro?: They run within 1.1% of each other on the same load — about 28 hours each on a refrigerator (full-size). Runtime will not separate these two; the deciding factor is somewhere else.
Which is lighter, the Anker SOLIX C2000 Gen 2 or Oupes Mega 2 Pro?: The Anker SOLIX C2000 Gen 2, by 3.2 kg (18.9 kg versus 22.1 kg). Both weights are manufacturer figures for the bare unit; cables and a solar panel add to whatever you actually carry.
Which model should I buy for my use case?: On the sub-scores that describe each use case: the Oupes Mega 2 Pro for home backup; the Anker SOLIX C2000 Gen 2 for camping & rv. They split, so the honest answer depends on which of those you are actually buying for.
