While I was watching an episode of The Walking Dead (which is a zombie show), a father watching a house tells his son, "it is as good as any"; what does it mean? First I thought, he wants to say, "it is like other houses" that is full of zombies. But I saw, they entered the house. So did he try to mean the opposite?
(I wouldn't say OP is "right" since there were two opposite meanings suggested.)
"As good as any" means choosing this house is "exactly just as good" or **equivalent to choosing any other house.** In this case, the word "good" has no connotation that "this is a good choice".
There's also a sense of requirement-to-make-a-choice without-any-knowledge. Suppose you have to disable a device by cutting one of three wires within 15 seconds. If you don't cut a wire, then of course disaster ensues. You have to cut one of them. You have to choose one. Whichever you choose is as good as any.
