You will get G.fast before FoD - that much I can say.
I heard my area won't be ready until next summer or autumn 2018. It won't be ready before xmas for my area. FTTPoD will be.
Don't forget that G.Fast is an 'up to' service (rate adaptive) so you'll always be trying to squeeze every bit of juice from your line (assuming you don't sync at the max 330/50). You'll constantly be wondering
Am i connected to the right type/make of G-Fast Pod?
Am i using the right type of G.Fast modem?
and potentially worst of all: will the dreaded DLM ever remove my banding?
On FTTP no such worries. You'll get a brand spanking new fibre optic cable installed all the way from the agg node to your living room and your ONT will ALWAYS "sync" at the speed you're paying for. None of this 'up to' rubbish or DLM to worry about. Reboot your ONT as often as you like
Of course FTTP is not immune from congestion but this is potentially the only possible problem you're likely to face on FTTP wrt speed issues. Not that i've experienced any speed issues on FTTP (touch wood)
