We've had TFC for over 5 years.
Of course it's ABS CBN only......no GMA
My wife gets pleasure from it but doesn't watch everyday.
There are some interesting programmes especially the travelogue ones.
Some programmes in English, but mostly in Tagalog. Some have English Subs
Some programmes really good, but mostly really not. Some pretty good news programmes

We used to watch it via internet (subscribed, can't remember how much though) Picture and sound quality wasn't that good back then, but I guess these days with much faster broadband speeds and HDMI connections direct to TV it might be OK.

We also have Apple TV connected via HDMI to our TV and so it's very easy to watch most of the GMA shows on TV via YouTube. Video and Audio quality for GMA programmes is highly variable.
