Many opinions here are rather polarised. I don't think that it's a simple choice between "fly manually and on raw data at all times, no matter the conditions and the complexity of the airspace you're in" or "don't dare to ever disconnect the AT and FDs and keep the AP engaged anytime above 200 feet". My opinion is that you'll be much better off using some judgement as to when hand flying for exercise is appropriate and when it isn't. Probably every airline flies to some places where you can fly manually anytime below RVSM airspace, do raw data or visual approaches etc. Think regional airports which are usually not too busy, have no strict noise abatement routings and a relatively straightforward STAR/SID. Somewhere like that is a brilliant place to practise flying the aircraft (although, sadly, some colleagues still won't take the opportunity). However, a busy major airport isn't really the ideal place for it. It's not only about you as PF, it's also about making sure that your PM has an acceptable workload which allows him/her to actually monitor and provide the much-needed safety benefit of a second pair of eyes. So, instead of keeping the PM busy doing selections which you as PF could instead do yourself with the AP engaged, allow him/her to focus on the safety-critical part of their role - monitoring the flight path and calling out any deviations, ATC, checklists. Ultimately, you're there to take the aircraft from A to B in a safe and efficient way - and sometimes automation can be greatly beneficial to this. The acknowledgement of that has nothing to do with passion for flying or lack thereof, as mentioned above.
