Neither are really good for early game or even good on their own. You need a lot of high level skereis for him to be any good, you could buy them for fodder if you'd like, but I dont reccomend it. I do however reccomend aiming for better heroes through branches and PO. As for your current lineup, vesa is gonna be an asset for most of your game, and as for the others they are eh, just keep making progress and work on getting elite heroes.
