I have both the pochette nm in DE and the Eva in DE, and I've found they both serve different purposes.
The pochette is best for carrying small items in a larger bag and having for those last minute, grab and go situations. Mainly I use it to carry my wallet, keys, and other items to the gym without having to lug my full work bag in, but have also used it for last minute drinks, or small midday errands. I do feel more self conscious using the pochette as a handbag, because it reminds me of the 90s super trend when these types of bags were really "hot"-- so I try to make sure I only use this bag for casual situations and usually never use the shoulder strap, but instead use it as a wristlet.
The Eva is more of a real handbag. I use her as a clutch, casual handbag, and hands free crossbody, depending on the event that I'm going to. I used to bring the Eva on trips as my main travel clutch, but now I mainly use my woc for this purpose. The Eva is great because it can be easily dressed up or down, and can masquerade as an evening bag, if need be. I have had some small hairline scratches on the front plate (I didn't baby her!), but I think she still looks great!
I hope that helps you with your dilemma!
