I ride my QB with albatross bars (exclusively for about 10 years now), for a few years I also rode a hillborne with drops with similiar reach measurements. for example I ran 100-120MM stems on my QB but 80MM on my SH with drops. like Jeffrey says your current stem may become an issue, the common rule of thumb is to add 2CM on stem because an albatross will come back 2CM, but 140MM might be too much stem, personally i've never had a bike with so much stem.
i might go as far as to say your bike is a little too small for you, but before that, what size is your QB? what is the effective TT? I would start adding those numbers up and see how they would translate to albatross. I don't think you have to add stem, if you just swap to an albatross you may find the 'natural' position to be in the hooks or bend instead of back at the grip--kinda like how the billie bar translates when you swap out an albatross.
as far as riding goes, that's very personal so hard to say in words, I will say the wide bars do feel good when accelerating on the QB, and I don't have issues with control, I do a decent amount of gravel riding and at times feel a little under biked but it still feels great on the trail. top of my stem is about level with saddle, so the grips on the bars do sit a little bit higher than saddle.
as someone that has been riding them for 10+ years i'm a fan, and when I had to reduce my bike stable to 1 bike, this is what I kept, partly due to how the QB rides overall but i'm sure part of that is the albatross--the only bar i've considered swapping it for is the Billie, which is just an albatross with more grip area!
