Not an Aigis specialist by any means, but I wouldn't call Aigis pure RTSD due to Orgia meter. For the same reason, her mix-up can be lacking. When she's not in Orgia, her pressure isn't really dominating. In other words, she's a quasi rushdown character since you also have to know how to zone with her while waiting for Orgia to recharge.
Lol, if you want punches/kicks, Elizabeth is totally not for you. She's probably the "laziest", holding that book/tarot card in her hand and only making minor gestures for Thanatos to attack.
