Aero bars: oval concepts vs. syntace

comparing/contrasting bars here. currently riding on syntace streamliners and am interested in the oval concepts bar. my question relates to height/drop differences between the two. can i expect to be more aggressive on the oval concepts bar vs. syntace. i like the adjustability of the oval bar and am trying to get more aggressive on my bike. was hoping the oval bar would be the answer to my problem. thoughts anyone? TIA
