I have had all 3! (but sold the 55)
Lyrik is stiffer and better damped than the Pike and even Push tuning the Pike does not give it the same confidence inspiring feel.
55 – Where do I start, mine had a wobbly axle and the standard spring (the only available iirc) is for whippets. This means you basically have a heavy, air fork (due to excessive air preload) which has inferior damping to the RS models.
Buy Lyric :)
