Bit late on this one, but next time you're in Manchester with a SystemOne AnyBus ticket, I recommend the RedExpress X41 to Ramsbottom thanks to the recent (possibly controversial) changes to the route! Comfy leather coach seats in a 2+1 layout and you get the whole motorway section (not that there's much of it left now
) of the route too all within the GM boundary! Also, the Stagecoach X50 is a route I always like riding, the fast link to Trafford Centre (which is even better with the new MMC's) showing you great views of the city (especially Deansgate, Salford Quays and MUFC) on the way there and back! Of course, the V1 (as discussed by others above) is my favourite route within GM without a doubt! Luxury buses that never fail to make me feel good (sleek buses, comfy seats, tables, luxury wood effect, great lighting, panoramic windows, etc.) and on a fairly fast route too! Once you're across the bridge to Salford, it runs direct on the A580 dual carriageway followed by a relaxing cruise down the full guided busway route! Definitely better than the V2, which only uses half of the busway, as well as the fact that Leigh is a bigger and better town with an actual bus station, a shopping centre (although not very big) and plenty of retail parks (massive Tesco nearby and a Lidl conveniently located on the stop just before the bus station if you wanna buy food) to keep you busy, not much in Atherton! 184 to Huddersfield (with a First ticket instead of AnyBus, you can actually ride the full route) is another one of my favourites, taking you through some breathtaking Pennine scenery beyond Oldham as mentioned above! You can also ride the Cityzap, which runs almost nonstop to Leeds, as far as Chadderton!
Just press the stop button as soon as it departs Piccadilly Gardens and the next stop is over there
