I'm pleased that my suggestion of the 1 lived up to expectations. The Fochriw section is quite dramatic and I think you did it in the right direction.
I agree with you on the 21 and I think the double run into Swffryd is good with dramatic views across the valley. I also agree that Stagecoach Cymru are pretty good, I've never had any missed trips or significant late running although I think I was on a 172 that got quite delayed due to the narrow streets and parked cars in the central section of the route. Can't really comment on Newport Transport, I have used them on the 60 between Newport and Monmouth and I think they used to run the 63 from Chepstow to Cwmbran too at one point, no problems here. Before that probably the 30 from Cardiff on a Metropolitan (that dates me!).
Blaenavon is worth a visit and there is more there than the average ex-pit village. The 31 across to Brynmawr is worth doing across quite bleak moorland. I think the few trips that go through Llanelly Hill might be the most dramatic I agree that the 172 between Maerdy and Aberdare and the 303 between Llantwit Major and Bridgend are probably the most scenic routes in South East Wales but there are good ones in Pembrokeshire and up into mid Wales too.
I am surprised the Llandudno to Caernarvon route was voted most scenic in Wales, yes it is good and relatively accessible but it is mainly along a dual carriageway! There are (IMHO) much better routes in Snowdonia (eg S2, S4, S97), also routes such as the T2 between Dolgellau and Porthmadog, the 30 between Abergynolwyn and Minfford and the X47/525 between Aberystwyth and Llangurig. Also the 42/43 between Abergele and Llanrwst - only possible on a Tuesday and needs careful planning - is really good while the 126 between Mold and Holywell is surprisingly dramatic - in a similar way to the 1 through Fochriw -and recommended for a short relatively frequent route. I strung together some inland sections from Mold - Holywell - Dyserth - Rhuddlan - Abergele - Llangernyw - Llanwrst on a sunny Tuesday in February. But getting very off topic here!
