IMHO the Fleischmann Twin Centre (& to a certain extent the Uhlenbrok Intellibox) will only become obsolete to people who require over 9 functions.
AFAIK the 27 speed steps on the TC is used for the older Fleischmann FMZ system.
Sometimes FLM are regarded as not being at the cutting edge, but the big thing to the credit of Fleischmann is that they support all of their previous products - going way, way back. If you are using FMZ you can still buy decoders & all the other stuff if you want to continue with FMZ. Other manufactures have marketed multi train control systems that are no longer supported.
Personally, I have though a lot about changing my TC's & using the ECOS, but the thing that puts me off if the apparent need to keep downloading upodates - I don;'t have time to keep our own website updated, let alone spending time updating my control system. Maybe the TC's that I use on SL are dated in the eyes of some, but fir the time being I'll stick to them.
