I picked Suns, but not with any certainty. If you break it down I reckon they just come out on top:
Backline - Suns - Suns with Thompson and May in the key posts, Harbrow and McKenzie playing smaller and using the ball so well coming out of defence, whereas the Giants have Mohr and Davis, however Davis cant stay on the park, whilst picking up Shaw and Hunt to add some experience down there. Suns also have gun recruit Koldashnniiinniny (or whatever his name is) who had 50 touches last week and is hugely rated.
Midfield - For mine, the Suns have the best midfield easily, though the Giants isn't that shabby, but still well behind the Suns. Ablett is the best midfielder of the two sides comfortably, with Ward on the next level. The Suns have Prestia, Swallow, O'Meara, Bennell, Rischitelli, with Martin obviously in the wings. Giants have Coniglio, Whitfield, Smith, Tomlinson who are very good, but a bit behind the Suns
Ruck - Mumford is the best Ruckman of the two sides, and Giles is probably next best. Zac Smith is a quality ruckman, but more on potential at this stage, whilst Nicholls shows a lot of promise. Boyd can also play in the ruck when he becomes established, whilst the suns have Doxon who can swing through there too
Giants have the better forward line, with 1 genuine forward star already in Cameron, with Patton seemingly a star and Boyd in the wings who could be anything. Suns have players that still have 'promising' next to their name, with Day, Lynch and Dixon, with none of those guys really grabbing a game just yet like the Giants forwards have. Matera adds some class in the Suns forward line, whilst the Giants seem to lack a quality small forward. Their talls though make it better overall
Still think that the Suns are just ahead, purely as their Midfield is stronger, defence looks better overall, and have potential in their forward line. But geez, both bloody good lists
