Not sure it's the 'best' but it's certainly one of them.
Not sure what's better, but I would certainly go branded from a 'high street' kinda store for the backup and cyclescheme side of things (assuming). Although I'd always push people towards LBS rather than big brands like Decathlon/Halfords/Evans' for the service side of things, but not many of them can even compete at that low level. So if you want cheap, buy cheap, but don't expect too much quality when it comes to components, build or servicing.
Can certainly get more/better second hand but a huge minefield, so equally far more likely to get ripped off/scammed.
