I disagree that his lyrics have gone downhill- i just think ASOP lacked any inspiration and the lyrics suffered massively. Come Clarity, in my opinion, is Anders' best moment lyrically- it has everything. Okay most people think 'Take This Life' is too emo, but i prefer to think of it as a song contemplating suicide (which it is), as opposed to cutting/harming oneself as part of a trendy scene.
Come Clarity has political themes (Vacuum, Your Bedtime Story), personal themes (Come Clarity, Our Infinite Struggle), apocalyptic themes (Versus Terminus, Dead End) and has such a variety- and all are pulled off with meaning but are still catchy. Very relevant lyrics to modern society. As opposed to ASOP, where it was all very generic and vague (apart from TCP- great lyrics there, i must admit).
I'm not a HUGE fan of sci-fi lyrical themes (Whoracle, Colony etc)- Reroute to Remain and Soundtrack to Your Escape had amazing lyrics too. Very thoughtfully wrote!
