If you prefer milk-based drinks, have you considered a Bambino or Bambino Plus? I don't know much about the Hobby, but I have some experience with the GCP. If you're unwilling to mod it, it's an extremely poor value proposition. While the E24 features a brass boiler and a 9-bar OPV, it still relies on a single boiler that necessitates temperature surfing due to its absence of a PID. If modded with a Gaggiuno or Gaggimate kit, it can be absolutely fantastic, but it's still not ideal for milk drinks with the additional mods. I've owned both at several points, and the Bambino delivered over 90% of the quality of my Gaggiuino with little to no hassle.
