Interesting comparison. I see them as even on paper offensively and defensively, so only the Ducks bias sways me to Lindholm, but can see how most would probably pick Ekholm given he's made more extended playoff appearances.
EDIT: This is actually really spooky close in terms of careers. Both at 0.4 PPG, both previously in non-Canadian markets, both averaged ~22 minutes a game (Hampus at 22:20, Ekholm at 21:40), career Corsi and Fenwick are basically identical.
