I think that the Optimus and IQ Tour are going to be near one another in terms of overall strength, but they're going to offer different shapes. The Optimus, being a pearl, is probably going to be a touch cleaner up front than the IQ Tour; however, the lower RG on the Optimus should mean that it still gives you some midlane. The biggest difference, in my opinion, is likely to be what you'll see down the lane. The Optimus will probably give more motion than the IQ Tour. Again, it depends on your style, layouts, coverstock prep, etc., but that is what I'd expect to see if I were you.
