Reaper is weird because he plays very different than the other flankers. He doesn't have a way on his own to actually close distance so you generally have to try and teleport somewhere secretly and actually drop down into the situation. It is something I'm very, very bad at which also makes me a very, very bad Reaper.
As for Bastion v Torb ... Bastion is a better Reinhardt buster and he also pairs better with Mercy than Lucio if your team is single support. In a more organized environment Bastion requires a ton of babysitting to be effective and Torb can use his turrets to shut down flank routes. They really fill two very different roles.
