The fact is that you a a player have a different desire to get each ability in the game. Whatever lists they happen to be on, you're going to want some abilities a lot and some abilities very little. When you select abilities off a list, you're going to take the abilities you want most first, and you're going to take the abilities you want least last. That should be non-contentious in any setup where we can assume that the player understands what he or she wants.
So if you make 10 selections from list A, the first selection will be your favorite ability off that list. Your sixth ability will be your sixth favorite from that list. And this is also important: since you're choosing your list, you're getting your favorite list. But if you make 5 selections from list A and 5 selections from list B, then your sixth choice is your favorite ability from your second favorite list. A first choice is almost always more valuable than a sixth choice, even if the first choice is only from your second favorite list.
So yeah, choosing five from one list and five from another list is almost certain to be superior to choosing ten from a single list. If there are any reasonable numbers of lists or vague attempts to balance those lists, you can pretty much guaranty that everyone will choose the two lists option.
Which brings us to another point: this proposed system is no different from not allowing people to multiclass at all. If you pick 2 classes out of 5, that's the same as there being 10 classes that happen to have a fair amount of ability overlap where you pick only one. It's one thing to have people write "Warblade/Warlock" on their character sheet, and frankly it's exactly the same thing to have the people write "Eldritch Knight" on their character sheet. There's nothing really gained from presenting this as a multiclassing situation, because it's functionally identical to just having hard rails character classes and having more of them.
