I am currently coming from an Allez triple : Tiagra/Sora : 50-42-30 and 12-25 ( I should notice a positive difference either way?)
You will NOT notice a positive difference if you want something EASIER. All those options are WAY harder than your 30f25r mix. I suggest that you get prepare yourself by NEVER climb in 30f25r with your current bike. Try to stay around 30f18r/20r so the gap to the new bike won't be too hard (kind of things that might make you regret your new bike (temporarily)). Also remember that the bike will not make the climb much easier, it never gets easier.
But to answer the original question, Your best option looks to be the Roubaix with Rival groupset. It has the easiest gearing of the group, and better components.
