If your insurance company did a replacement camera rather than giving you the money then it would be down to them to decide which cameras would be the nearest for the 5D.
Sony keep changing their range of products - cameras especially as far as we are/I am concerned - extremely quickly. To answer your question is maybe impossible to get the a77ii as the answer
Some people may say that the 5000 or 6000 type range could be the replacements for the 5D? But you could argue that the lens mount is different and you wouldn't be able to use your existing A mount lenses!
Some members have these and are very pleased with them.
