I'm narrowing it down... I just need your help!

The ergo is a great design but bulkier than the others you mention which are pouch slings (the ergo is based on the asian mei tai carrier, less bulky versions are babyhawk, ellaroo).
We have pouch slings and mei tei and ergo. They all have different uses. We found up till recently the mei tai best, but we have started to use the ergo more now as ds is heavier ( the ergo can hold the weight better for you back long term). The pouch sling is handy for up to 30 mins, I`d never wear it to walk to the shops, but I would wear the mei tai or ergo to the shops. All of them are worn around home and as for feeding, hmmm , well I am still trying that out. I did successfully feed ds when he was 3 mths in the mei tai when we were having lunch in a cafe, but so far I have not found it very easy to do.

I had a bubba moe, I hated it, I sold it as DD hated it too. Found it really big for her and she kind of got lost in there and really didnt like it.

I think the peanut sheels are a bit smaller and might be better.

We actually really like the baby bjorn. I find it really comfy and she has loved being uprigh from about 4weeks old so it works for us.

Maybe you can take her to babies galore and try DD in their slings and see what works for you girls.

hun I really have to recommend the close carrier - its just fabulous

I do not like one shoulder slings at all. They make one shoulder quite stiff very quickly. I wouldn't use one for more than about 10 minutes... quickly ducking into the shop.

Structured carriers like the Baby Bjorn are ok, but a lot of people find that their bubs throw their heads back a lot and seem uncomfortable. I have one and cant get my baby in and out on my own, her legs get stuck .

I have tried a close carrier and loved it so much I am getting one. For me, wraps are just the best!

OK, based on everything you have said, you may well find that you want a quick and easy, in and out carrier like a pouch (great for newbies, and short wears for older babies, generally easy to feed in if your bub is happy to be in a cradle carry, not as easy to feed vertically in as they can't be adjusted but still do-able, sized to the wearer, so not good if dad or someone else wants to wear too), and something like an Ergo for when she is bigger.

An Ergo really comes into its own as a toddler carrier, especially for back carries. I personally found it difficult to feed in, because it is rigid enough to prevent a sufficient 'drop down' when loosened to move bubs down to the boob (this is pretty easy in a mei tai, but not so easy in a carrier with a very heavily structured waist band and seat darts like the Ergo).

Most in-carrier feeders that I know of prefer ring slings, wraps and mei-tais for feeding, as they can be loosened and tightened to bring baby to and from the boob. Sure, they have a slightly longer learning curve than a pouch, but a pouch may not give you this flexibility, I've heard that this can especially be problematic for women with large breasts.
