It depends...
Upgrade on the 777...3 long hauls, 15-18 days off and less than 2 landings a months (exactly what a 200hr cadet needs to finesse his/her flying skills).
A330...15-25 sectors a month, 8-10 Gs with a few O days to screw with your roster, lots of India, split duties and Asian turn around and overnight flights - no 3 man crew till you get your RQ.
Training...as usual in CX depends who you get but generally good...most trainers wanna get the best out of you so it's up to you to a certain extent. Don't get bogged down with tech stuff...what counts is route knowledge, NPs and OPS-A...
Hope this helps...
