You don't join LH for the flying, it's all about the lifestyle..
Long Haul flying allows you to see the world (rather than just an airport) but once you've flown 'the big jets' it really is just another aircraft and it also comes with many negatives such as ie Jetlag, fatigue, away from family etc etc... Having said that, I've been LH for 22 years and couldn't see myself going back to SH unless I needed to.
It's a personal choice and certainly no better/worse or right/wrong with LH vs SH, but do your research and make informed decisions rather than just wanting to fly a bigger aircraft etc.
