G1 transformers or the Present Transformers: Movie toy & Prime toy line?

Help, I'm starting to collect transformers since 2006 but apparently I think G1 transformers are starting to get extremely rare (but i don't have any of them yet, both sides),
but I do have the movie transformers (autobots) and I think I'm still missing [the three arcee, mudflap, skids, leadfoot, topspin & jazz]
so should i get the G1 or the transformers Prime......
also I want an answers from a collector with experience in this things.....^_^ thanks very much in advance
