I love mine. It's got great wrist presence without being obnoxiously huge. The flat bezel helps it wear a bit smaller than one would think. It's got the P9000 inhouse movement with a 3-day power reserve. Brushed titanium with a very unique dial. What more could you want?
Not sure what else to say if you had a choice between the two. If under a 2k spread its a no brainer. Unless you are comparing retail prices where there is a 5k spread, I would consider the 305, but if you used values 233 all day everyday and twice on Sundays.
