I find mine to be very good all told and feel quite lucky that our area in West Oxfordshire has a blanket rollout to even quite remote properties.
I do see some congestion occasionally, although i think that this is fairly inevitable with a high bandwidth connection. I dont test very often these days as i have been a customer for a while now, but it will usually always show the same ~940/940 type results to select speed test servers if you pick a few and find the best one.
Wireless you should never expect to see very high bandwidth, my APs are fairly old now (i run 4*Meraki MR33 items) and although i have very good consistent coverage via these, they hit nothing like 1gbit.
In short i think the GC network seems pretty good, generally congestion will be felt only on links out to the wider internet or elsewhere.
