I never tried the tripple brain but I agree that it does not make sese to choose based on the score(I thought that it choose also based on the main line(for example if engine A see the same main line faster than it is logical to suspect that engine A is faster in that position so it may be better to prefer engine A) I read a claim that it worked on test suites with specific 2 engines but test suites are usually to find moves and not to avoid moves. It is known that programs that solve faster usually find better scores so I think that using test suites when the target is to find a move is clearly misleading and if people want to use test suites then it is better also to use avoid move tests and in avoid move tests I expect the program that does not solve the position to show higher score.
