Free tv is always a good thing. 
I like the various genre of stuffs shown in one chn. There seemed
to be more spontaneity but with so much stuffs nowadays, they need
to be segmented.
That aside, whatever happens to the identity between the two
channels? They should be a niche in their own way to attract a
loyalty following. If Chn shows loads of SG produced dramas plus
those charity shows.. so be it. If chn U shows more Korean/Jap
stuffs...so be it. Least, as a viewer... we know wat to expect and
to the advertisers... they know which chn to broadcast their
adverts to penetrate to the relevant audiences.
Yah, I sound paraniod maaaaaaaaaaaaan.
