It is more likely to underwhelm than overwhelm.
But it really depends on your level and to some degree your attitude.
Ride it fast and it can be good fun, it is also a physically tougher loop than it might at first appear, especially in winter.
What I would say is if you are looking to go and murder the life out of it then weekends are best avoid, especially if the weather is reasonable. It is a great place for families and improving bikers and any attempt to Strava a section is likely to end in fustration.
Now i’d better go get the bikes sorted as my son and I are heading there later. He is 15 now and we have ridden Afan, Cwmcarn and Surrey Hills over the Xmas break but still enjoy a chilled loop at Bedge.
