52/42 or 50/39
I am fixing up a Carrera TDF 2012 that I picked up for £10 in awful condition (a decent frame & handle bars, with a mangled chainset attached). I don't want to spend much money on it and don't need to win any races, although I might enter a sportive eventually. I've used a bunch of old parts I had lying around (wheels, brakes, new cables, cassette) and bought new bits and pieces (tyres, tubes, brake pads, rear derailleur, head set, front fork, chain).
I need to replace the chainset and the viable options are a Miranda 52/42 and a Shimano 50/34. I'm riding on the Antrim Coast Road which is fairly flat, and am fairly fit, even if I'm a little overweight.
Any advice?
(Save up and buy a new bike is what I expect to be told, but something more specific to the chainset is what I'm hoping for. Thanks guys.)

If I was visiting your area with a bike I would use the 50/34 as I see there are some steep climbs (Torr Head) that look interesting. No real advantage to the 52/42.

Depends what gears you're using in the freewheel but I agree that going for the larger size chainrings will not offer any benefit. What size are the crank arms?

If your plan is to enter more demanding sportives, a compact crankset will be your friend when you approach climbs later in the ride.

Since whatever cassette you end up with will probably have an 11 on it, you're highly unlikely to need a ring bigger than a 50. The only reason to go with the 42/52 would be to remove the outer ring and set it up as a 1x.
