I feel if you're gonna have them coexist is that the major difference is G1 Megatron has genuine good intentions, warped as they are, behind his methods. He wants Cybertron to prosper, no matter what state it's in.
BW Megatron sees that and only focuses on the power he held. He wants everything for himself. G1 Megatron would never stoop to the lows BW Megatron would like killing his most loyal men or assimilating all of Cybertron to supplant Primus. G1 Megs would be disgusted by him.
