The Legend is very bass-y. The SP is fairly neutral, which is how AK tunes its devices. I wouldn't touch an iBasso of any type after having had three AK's (I did have an iBasso at one point). But if money is the object, you have to do what is best for your wallet. Oh, and people's opinions are just that. They might like more or less warmth or brightness, they might have musical tastes different than yours, they might hear things differently than do you. No one here is the last word. The best way is to try things at a CanJam or at a dealer's showroom, if possible. If you can't do that, then ask as many people as possible, figure out who makes the most sense to you, and then buy the thing knowing you might end up selling it.
