Have to agree with Jonathan.
Was the same B747 vs L1011 in the eighties, then in the 90's the -400 got the best rosters. 'bus was okay into the noughties while the 340's were flying, the B777 ate !!!!!. How time changes!
I've flown them all, some good rosters, some bad. Like Jonathan said; get some time in - no instant gratification here.
