I've not tried either (we have an Ergo), but I have a few friends who have the Manduca and I really like the look of it, especially that you have the option to cross the straps at the back. It looks more comfortable to me than an Ergo and if I had it to do again, I'd probably get one of those instead. I would try to get yourself to a sling meet if you can and try both though. I think Manducas tend to be a bit longer in the torso section, so they can be well suited for taller people. I know my Ergo is a bit short for me in a back carry, I'm 5'9, so I can only really do front carries in it. I don't know much about Connecta though.
