I like it when they repaint/retool old toys to pad out these lines. You get some neat new colors sometimes! Bomber-Megatron, for example - there's a toy I might get again, despite the Bay-head. Obviously not a big fan of movie-verse, but the one nice thing is when they run out of movie characters and start expanding into G1 (especially within these exclusive sublines), with some decent G1 reduxes (i.e. DotM Cyberverse Powerglide - although that one wasn't a subline exclusive).
