Element, Zebra, the one at plugin boutique that they make, triangle, Korg legacy collection, ofcourse the System-1 plug-out synth. the Ni Kontakt stuff can get pretty cool too.
I think the new kid on the block atm is probably xfer serum, which is a really powerful wavetable synth that makes massive look, well, a bit small and limited.
The usual ones; Massive, Sylenth1, Nexus, FM8, and a few more. Synth1 is also on the rising as I've noticed.
I've also noticed that people have started mentioned U-he Diva more and more (I could be wrong though).
Then we have Serum, which is steadily building up its reputation, and I feel I'm just waiting for it to completely explode in popularity.
